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?

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...

With what operating systems is the program compatible?

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

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.

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.

*Info taken from

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)"

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 utilities 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.
