IMPORTANT: Note that many software-related issues can be resolved simply by making sure you have the latest  version of the program installed. Updates for our programs are released periodically that contain new features and bug fixes. In many cases, if you are encountering a problem it may have already been addressed in an update and you'll only need to install the update to fix your problem. There are usually two versions of the program available at any time - the current official release and a beta version with the most up to the minute changes.

Frequently Asked Questions

What is the current version of TRAXPro?

See the TRAXPro page for the most recent version:


How do I check my version?

To check the version of the program you are running, select Help from the main menu and click on About... .


I received a file from a colleague that is in .TF2 format and I cannot open it in TRAXPro. What's wrong?

With the changes made in TRAXPro 2.0 we had to update the file format for TRAXPro data files.  The new format is .TF2 where the old format was .TWF.  If you do not already have the new version, you can get the update                                                             .    As soon as you have Traxpro 2.X.X installed you will be able to open and use the .TF2 files just like you could the .TWF files previously.


I have a .DMP file from the download, but it does not show up under File=>Open.  Why can I not open the .dmp file?

.DMP files can be opened from the File>Open menu, but you must set your file type to "Traxpro Dump files *.dmp" in the lower left of the open screen.  You can also set it to "All Files." Once you do this you should see your .dmp files and can open them up.


My Comments aren't beings printed on the report. What's wrong?

You may not have selected to print them in the report setup. Select File, then Print to access the report setup. Once in the report setup, click on the Headings-Page Number tab and be sure there is a check in the Print Comments box.


If the Print Comments box has been checked and the correct comments still are not coming up in the report, check how you have entered the comments for the file. There are two areas of the program where comments are entered. The Preferences selection of the File menu allows you to enter general comments that will be applied to all studies, such as Weather: or Counted By:. To fill in this information for a specific file, when the file is open select Edit Count Header from the Edit menu. The Comments field of this screen lets you choose from the defaults you've entered in the Preferences and add specific information.


With what operating systems is the program compatible?

TRAXPro is compatible with Windows Operating Systems XP, Vista, 7, 8 and 10.


How do I interpret the information provided in the reports?

Refer to the Interpreting Reports chapter of the TRAXPro manual, or view the Reference Page.


My computer does not have a serial port for download. What can I do?

All JAMAR equipment that interface with a computer currently use a serial (Com) port to do so. However, if you do not have a serial port on your computer (or there is a conflict with another device), you can use a USB port by using a USB to Serial Adapter. These devices allow serial peripherals, like JAMAR equipment, to interface with a USB port.  More Details.


What does 'classification' mean? What do the classes stand for in a standard classification study? What are unclassified vehicles? What causes them?

In traffic terms, a vehicle's 'classification' is the category it is sorted into based on its physical characteristics. Most classification studies are done using the Federal Highway Administration's Scheme F.  More Details.


The Found New Hardware Wizard popped up when I connected my TRAX Flex HS to the computer. What does that mean?

The first time you connect the USB port of the TRAX Flex HS to a computer, you must install the drivers for it.


I am having trouble downloading or processing my data and I need to send in the Dump file (.dmp). How do I do this?

Here is how you can find the .dmp file from your download.  The default location of all .dmp files is C:\Program Files (x86)\JAMAR\TRAXPro, however you can change the location where they are downloaded to so you may need to check that particular setting.


If you have TRAXPro 2.0, or later we now save each download as its own .dmp file.  The format if the file name is now TPDxxxxxxxx.dmp where the xs are a time and date code.


You can check where the .dmp files are downloading to by opening TRAXPro and going to Download Traffic Recorder, then choose the appropriate counter. If you are using a Trax Apollyon this will bring up the download screen.  Above the 5 traffic lights is a field that says “Sending Temporary file to:" and there is a data path listed.  This is where your .dmp files are going each time you download.


If you are using a Gen 1 Radar Recorder you will select the correct radar and on the download screen you can click the “Change Folder” button and see what folder is highlighted.  That folder is where your .dmp files are.


*Note* Black Cat Radars do not download .dmp files, they download .dat files. (See next question below for details on finding .dat files.)


Once you know what folder to look in you need to find the appropriate .dmp file to send in for troubleshooting.  You could have several .dmp files, so the easiest way to find the file in question is the check the file created time and date.  This can be done by setting the folder view to details and looking at the date and time shown.  Find the file that corresponds to the time when you did the download in question and email that file to


To email the .dmp file to us at JAMAR just compose an email in your email client and use the attach function within the email client and simply browse to the specified location and select the file Traxpro.dmp and email it to  You can also ‘right-click’ the .dmp file, and then select “Send to”=>”Mail Recipient” and this will bring up your email client, from here just send to


Be sure to put your Name and contact info as well as a brief description of what exactly is happening and any error messages your receiving.


How do I find the .dat file from a Black Cat Radar Recorder download?

The default location for the .dat files, which are the BCRR equivalent of the TRAXPro .dmp file, is C:\My Documents\Jamar\TraxPro.


The .dat files are all numeric values for names so finding the one that corresponds to your recently downloaded traffic count must be done by date.  If you set your folder view to “Details” you can check the ‘date modified’ column and find the time and date when you ran the download of your BCRR.

Each download done makes a .dat file which will have a time and date modified of the exact moment you initiated the download.  This is how we find the .dat file for a specific count you downloaded. If you do not recall when you downloaded the file, then there is no easy way to find your data other than going through each file one at a time and hoping you can recognize the site code or start and end times of the count.


How is the 85th percentile value calculated in TRAXPro?

In TRAXPro the 85th percentile, when dealing with Binned Data*, is calculated as such:


Let's say we have a count with 1000 vehicles total, the software takes that 1000 vehicles and multiplies it by .85, in this example it gives us 850.


1000 X .85 = 850


The software then looks for the 850th vehicle in the count.  So, the software finds the 850th vehicle and that vehicle fell in the 55-60mph speed bin, and as it happens there are 10 vehicles in that speed bin.  The software then evenly distributes all 10 vehicles within the 55-60-mph speed bin (2 vehicles at 55mph, 2 vehicles at 56mph, 2 vehicles at 57 MPH, etc.).


The software then finds the 850th vehicle and in this example well say that it was one of the 58mph vehicles in the bin, therefore the 85th percentile is 58mph.


*With Binned Data the 85th percentile calculations may be off by one MPH from an absolute 85th percentile, such as you can get from Per Vehicle Data in TRAXPro, if any rounding needed to be done within the distribution.


In Per Vehicle data we have the exact values for each and every vehicle in the data so the software gets an exact 85th in the stat report.  This works much the same way, the software lines up all the vehicles in the study in ascending order by speed.  Then it takes total vehicles times .85, and that value it the number of the vehicle whose speed represents the 85th percentile.  What is 85th Percentile?

I cant see my network drives on Windows 10.  How can I fix this?



This section contains steps that modify the registry. Incorrectly editing the registry may severely damage your system or make your system unsafe. Before making changes to the registry, you should back up any data on the computer. For more information about how to back up and restore the registry, see article 322756 in the Microsoft Knowledge Base (


To work around this problem, configure the EnableLinkedConnections registry value. This value enables Windows Vista and Windows 7 to share network connections between the filtered access token and the full administrator access token for a member of the Administrators group. After you configure this registry value, LSA checks whether there is another access token that is associated with the current user session if a network resource is mapped to an access token. If LSA determines that there is a linked access token, it adds the network share to the linked location.

To configure the EnableLinkedConnections registry value

1. Click Start, type regedit in the Start programs and files box, and then press ENTER.

2. Locate and then right-click the registry subkey HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System.

3. Point to New, and then click DWORD Value.

4. Type EnableLinkedConnections, and then press ENTER.

5. Right-click EnableLinkedConnections, and then click Modify.

6. In the Value data box, type 1, and then click OK.

7. Exit Registry Editor, and then restart the computer.

Known Issues & Solutions


I am getting Runtime Error 6, 9 or 13 when I try and download and process my count data.

These errors generally indicate a problem with the formatting of the data.  To correct the issue the .dmp or ‘Dump’ file needs to be emailed to us here at JAMAR.  In the current version of TRAXPro you can send the .dmp file by using the ‘Open Support Incident’ tool in the Help menu.  You will want to fill this form out completely.  There are two lines toward the bottom.  The first labeled ‘Dump,’ will let you attach the .dmp file.  All you need to do is click the button with  “…” next to it.  A file selection window will open showing the contents of the folder that your .dmp files are set to download into, you should only see the .dmp files in that directory.  Now, if you have a pre v2.0 installation of TRAXPro you will only have one .dmp file called Traxpro.dmp.  If you have v2.0 or later you may have several .dmp files.  All of them will begin with TPDxxxxxxxxxxxx.dmp.  What you want to do to find the correct file to attach is right click on a blank part of the window and select ‘view’, then set the view to details.  Now you can see the dates and times of the files.  You want to find the one with the correct date and time, normally in this kind of situation, it will be the last file chronologically.  Once you have the .dmp file attached, if you have a data file saved in basic data format, you can select that one the same way as the .dmp file.  Once the form is all filled out just hit “Send support request.”


Error message reads 'You do not have the correct Excel Version' when you try to export data to Excel.

This error was generally only occurs in version 1.0.6 of the program and was the result of a support file being left out of the installation for the version.  This was corrected in version 1.0.9 and subsequent versions. Download the latest version.


Run Time Error 5 occurs when trying to use the Open command to retrieve files.

This error is related to the configuration of some computers and can occur in versions 1.0.6 or earlier. It was corrected in version 1.0.9 and subsequent versions through modifications to the file retrieval commands.  Download the latest version.



Basic data collected in L2 layout does not process correctly.

This error is related to a bug in the default layout used for L2 in versions 1.0.9 and earlier. This was corrected in version 1.1.8 and subsequent versions of the program. Note that for the correction to take effect you need to uninstall your previous version before installing the latest version.  Download the latest version.


Error message reads 'The current interval is not one greater than the last interval' when attempting to process a file.

This error is usually related to a problem with the data format that has been sent out from the TRAX. In most cases the error can be corrected and the data retrieved.  When downloading a TRAX, a temporary file named traxpro.dmp is created with the data as is comes out of the TRAX. The default location for this file is C:\Program Files\JAMAR\TRAXPro, although it can be sent to a different location based on the path select in the download screen. If you encounter the above error, locate the traxpro.dmp file on your computer and e-mail it to the support department at along with a brief message stating the problem.  Since the traxpro.dmp file is overwritten with each download, be sure the problem file is the one you have downloaded last before looking for the file.  Update: Beginning with version 1.4.1, TRAXPro contains additional error checking to allow it to recover from this problem and process your data. If you are using an earlier version, download the latest version, then try the download again.


Run Time error occurs when trying to access files using the Open command of the File menu.

This error generally occurs if the path last used to access files is no longer accessible. This can be caused by the the path being deleted or renamed, or if the connection to the path, like a network drive, is down.  To correct the problem, start TRAXPro and then go to the Tools menu and select Utilities. (This is only available with version 1.3 and higher. Download the latest version if you are using an earlier version.) In the utilities menu, select Change Data Path and reset the path.


Run Time error 380, Invalid Property Value, occurs at the conclusion of data download.

This error is generally caused by the end-of-file marker being missing at the end of the data. To get around this, start a new count with TRAX and let at least one interval of data get stored. This will create a new file with a new end-of-file marker for the download. Once the new file is created, download the TRAX again and the list of stored files should come up correctly.


PDF files generated by TRAXPro appear blank in Adobe Reader.

This problem appeared when Adobe released version 7.0 of its Reader. PDF files generated by version 1.4.2 and earlier of TRAXPro would open in this version, but all pages of the report would be blank. The PDFs would appear normal in earlier versions of Adobe Reader.  Some changes were made in TRAXPro to compensate for this change from Adobe and the problem was corrected in the 1.5.3 release of TRAXPro.  Download the latest version.


Run Time Error 9 occurs at the conclusion of data processing when processing basic data.

This problem affected certain types of data sets where the data fit a specific pattern. This was corrected in version 1.5.3 and subsequent versions of TRAXPro.  Download the latest version.


When attempting to open file, get message 'There is currently no support for 'XXX' type files', where the letters XXX change from file to file.

This problem occurred if the combined data path and file name for a file exceeded 120 characters. Once the 120 character limit was reached, the program used the next three characters as part of the error message for the file type. This has been corrected in version 1.5.3 and subsequent versions of the program.  Download the latest version.


When a new user logs onto a computer that has had the software previously installed, they are prompted to enter the serial number for the program.

The serial number of the program, and several other settings, are stored in the Windows Registry of the computer under the Hkey_Current_User location. Since this entry changes for each user of the computer, the serial number must be entered by each new user.  Once this has been entered for that user, it will not have to be re-entered.


After installation, the program displays 'Evaluation Copy - Limited Functions' in the title bar even though a fully licensed serial number has been used.

This problem can occur if the serial number for the program was entered without the dashes (-) that separate each set of four numbers in the serial number. To correct this, go to the Help menu and select Enter New Serial Number. Place a dash between each set of four numbers, then close the program and restart it.


Error message 'An overrun occurred on the communications port' appears during the data download.

This error message usually means that the computer was not able to keep up with the data that was coming in during the download. It most often occurs during longer downloads and short downloads of data may work on the same computer without error.  There are several things that can be done to address this issue. The first step to try is simply rebooting the computer. If the computer has been running for a while, and has a lot of applications being used in memory, it may not be able to keep up with the processing of the downloaded data. You may also want to try lowering the speed of the baud rate that is selected in the software.  If these do not help, or if the problem occurs consistently, the communications port may be getting interference that is limiting its function. The best long term solution to this is to bypass the serial port by using a USB to Serial Adapter. These devices allow you to plug into a USB port and create a new communication port for the computer.  More Details.


When I process my data all the vehicles show up as motorcycles or they all show up as busses.  What is going wrong with my data?

Generally when all your vehicles show up at one extreme or the other, be it for classes or speeds, it has to do with the way the tube was laid out in the road.  If the road tube spacing setting in the TRAX Traffic Counter is smaller than what was actually set on the road, you will see all the vehicles show up as going very fast, and class wise they would all be motorcycles.  If the tubes on the road are set wider than the value set in the counter then all the vehicles would appear longer (buses maybe) and the speed report would have them going much slower.  If you find your data looking like either of these then the first thing to check is the Sensor Layout Tab on the basic data screen.  The top window on the right side is “Sensor Spacing” this is the setting you need to check.  The value in the window is in inches.  So, if you put the tubes out at 2 feet then you want to input 24, if you put the tubes out at 8 feet then you want to input 96.  The EZ Belt is 4 inches but we have found that due to simple physics that 4.33 works better than 4 inches for the EZ Belt, so if you use the EZ Belt you want to input 4.33.  Once you have corrected the tube spacing then you can just hit Save and Process and process out your data as usual.  If you have had to make the above changes, that means that the setting in your counter is probably not set correctly for how you set your tubes.  To check the spacing in a Plus Counter you go to UTILITIES=>DEFAULTS=>SPACE and simply input the proper value for your preferred tube settings.


I am getting Run Time Error 52 when I start TRAXPro.

This error indicates a problem with the ‘Recent Files’ list.  It is a relatively fast and easy fix, but you MUST have admin access to your PC.  If you do not have local Administrator access, you will need to get someone who does to do this step.


**WARNING**  This fix requires that you enter the Windows registry.  Errors made in the Windows Registry can cause major computer problems.  Be sure to do nothing other that which is stated in these instructions.  If you do not feel you are familiar enough with computers then it is best to find another who can do this with confidence.


With all programs closed go to Start=>Run and type in ‘regedit’ and hit OK.  This will launch the Registry editor.  On the left side you will see a folder tree.  Scroll to the top and find HKEY_CURRENT_USER and click on the plus box next to it to expand it.  Under HKEY_CURRENT_USER find ‘software’ and click the plus box next to software to expand.  Now scroll down until you see ‘VB and VBA Program Settings’ and again expand it with the plus box next to it.  Now you should see the listings for TRAXPro.  Expand the appropriate one and then look for ‘Recent Files’.  Click one time on Recent Files.  This will highlight the folder and the icon will change to look like the folder is open.  You will also see some lines of text appear in the right window.  With ‘Recent Files’ selected and only ‘Recent Files’ selected, press the Delete key on your keyboard.  You will see the ‘Recent Files’ folder disappear. Now simply hit the X in the upper right corner to close the registry.  Now you can open and use the program.



Run Time Error 75 (this error can appear in a variety of situations).

This error can appear in many parts of both TRAXPro and PETRAPro.  However, it always means the same thing.  Permissions.  RTE 75 is a permissions issue, you may not have the right permission level for the drive that you’re trying to save a file to, or open a file from.  This same error can also take the place of several other errors which may tell you that you don’t have a certain permission level in windows. You may not have the right permissions in the registry for some of the functions in the programs to work.  The way to correct his is to have your administrator open up your access to that area.  If it is a network drive they need to make sure you have read/write/modify access to that drive or specific drive location.  You may need to unlock access to

C\Program Files\JAMAR as well, you would want full read/write/modify permission to this folder and all subfolders.  If the error happens when simply doing a function in the software that usually indicates that you are locked out of the registry entries that need to be free.  To fix this you need to have an admin unlock the programs registry key.


**WARNING**  This fix requires that you enter the Windows registry.  Errors made in the Windows Registry can cause major computer problems.  Be sure to do nothing other that which is stated in these instructions.  If you do not feel you are familiar enough with computers then it is best to find another who can do this with confidence.


The Keys that need to be unlocked are:

HKEY_CURRENT_USER\Software\VB and VBA Program Settings\Traxpro


HKEY_CURRENT_USER\Software\VB and VBA Program Settings\Petrapro


To unlock them you simply right click the key and select permissions from the list that appears.  Add the user to the full permissions list, then close the registry.


'An error occurred in TRAXPro module SETTING_SAVE' occurs when clicking OK in Preferences.  This is then followed by a Run Time Error 75.  This is followed by an Error 440, and the program crashes.

This error can occur in both Windows Vista and Windows 7 operating systems.  It comes from new security features in both of these operating systems.  To fix this you simply need to set the "Run as Administrator" option.  To set "Run as Administrator you simply need to 'right click' (that's the other mouse button) on the program icon (TRAXPro or PETRAPro), which can be found on your desktop or in the start menu, and select "Properties" out of the menu that appears.  On the Properties screen you will want to click to the 'Compatibility' tab, check the 'Run this program as an administrator' box (as shown below), then hit 'OK.'  This should now let the program run properly in either Vista or Windows 7.  Once set, this should not need to be reset until such time as you have cause to remove and reinstall, or if you do an update from JAMAR's website.  After these types of modifications, this "Run as Administrator" setting will need to be reapplied.


My TRAXPro or PETRAPro keeps prompting me for Administrator Credentials in the User Access Control (UAC)  I am not an administrator, how can I get rid of that?

In Windows Vista as well as later in Windows 7 Microsoft added the User Access Control, this was done for security purposes to make sure that you the user are in control of your PC.  This has led to a few complications, however, one of them being that certain customers who are not Administrators on their own PC, will be prompted for Admin credentials every time they attempt to launch TRAXPro or PETRAPro.  The solution for this is quite simple.  There is a file for each program known as the manifest file.  You simply need to delete this file.

For PETRAPro the file is C:\Program Files\JAMAR\Petrapro\Petrapro.exe.manifest

For TRAXPro the file is C:\Program Files\JAMAR\Traxpro\Traxpro.exe.manifest

If you had previously set the programs "Compatibility Mode" to "Run as Administrator" you may need to uncheck that after removing the manifest file.

*Note*    If using a 64 bit operating system, the Program Files folder will actually be “Program Files(x86)"




When I try an download my traffic counters on my Windows 7 or Windows 8 computer, I get an error saying, "Runtime error 339: Component MSCOMM32.OCX or one of it's dependencies not correctly registered: a file is missing or invalid."


*Update 5/22/14*


We now have a batch file that will automate the process below.




To use this, download the file TRAXPro Batch and unzip it to a folder. Once the file is unzipped, open the folder and

right-click on the file TRAXPro Batch File.bat and select Run as Administrator.


You will then be asked to select if the

computer you are using is a 32-bit or a 64-bit system. Select ‘1’ for 32-bit or ‘2’ for 64-bit and press Enter.





Runtime Error 8020 and 8002 when connecting via Bluetooth.

If there are complications when hooking up your Radar Recorder and adding it as a device in Windows, you may receive either the Run Time Error 8002 “Invalid Port Number” or 8020 “Error reading com device” when trying to connect to it in Traxpro.


The first thing to do if you get this error is make sure you have the right port selected in Traxpro.  Check the drop down selection and make sure you are set on the radar recorder you are trying to connect to.  Also, check that the battery has enough of a charge.  A low battery can affect your ability to connect to the Radar Recorder (the best method is to use a voltmeter directly on the battery terminals).


If the COM selection is correct and the battery has enough of a charge but you are still getting the error, the next step is to repair the device in Windows. In “Devices and Printers” delete the radar, then hit “Add Device” and let it re-detect it, then input the pairing code and allow it to install.  Once it appears, the unit can take several more minutes for the drivers to fully install.  To check the status of the drivers you can double click on this icon down in the System Tray in the lower right corner of your screen.


Once the drivers are properly installed, you can check Traxpro and the port should appear in the COM port drop down, listed as the radar serial number.  At this point try the connection again.


If the error still comes up, one final step that has seemed to work sometimes is to move any port values to below 12.  So if your Radar is trying to connect on COM 20-something, sometimes moving it to a lower number will stabilize the connection.


To do this, go into Device Manager and find the Radar’s connection under “Ports (COM & LPT).”  Right click that and select “Properties.”  In Properties there will be a “Port Settings” tab along the top of the window.  Go to that tab and then click the “Advanced” button.


Set the com port to something lower than 12, then hit "OK" All the way out, and try your connection again.


3rd party Bluetooth Clients

Many Bluetooth capable computers, as well as external Bluetooth antennas, come with their own Bluetooth utilities client.  These can interfere with the setup and connection of your Radar Recorder.  The Bluetooth utility that comes with Windows works perfectly fine.


If that shows up go into the Control Panel, and into programs and features and we want to remove any and all Bluetooth clients.  The Bluetooth utility that comes with windows works perfectly fine.  There are several other 3rd party Bluetooth utilities, it is best if any and all of them are not used.


To find out if a 3rd party Bluetooth utility is being used, double click on the Bluetooth icon in the system tray, in the lower right corner of your Windows Screen.


If so, you will see a screen like this (or something other than the Windows utility shown above).


In that case, go into Control Panel, and then into "Programs and Features".  We want to remove any and all Bluetooth clients.  If you have other devices or systems that use Bluetooth, then you would want to make sure that those do not require any of these 3rd party utilites before removing them.


So once we have the 3rd party software uninstalled, we can remake the connection to the radar and try to connect to it in Traxpro once more.
