Track IR not working in Prepar3D (P3D)

First Test Track IR is connected:

Is the tracking working properly in the Track IR software? Track IR should be working properly there in order for it to connect to Prepar3D. Track IR should also be launched prior to starting your game.

Navigate to the location where P3D was installed. By default this is the C:\ Drive. The simmconnect.msi files will be located in the folders listed below. Double click on them to reinstall them. If they are not installed, you will need to reinstall Prepar3D.

• C:\Lockheed Martin\Prepar3D v4\redist\Interface\FSX-SP1\retail\lib\simmconnect.msi
• C:\Lockheed Martin\Prepar3D v4\redist\Interface\FSX-SP2-XPACK\retail\lib\simmconnect.msi

You will have to show file extensions to make it easier to identify . To do this, go to the View tab, Show details, And make sure File name extensions is checked.

Once these are reset, reboot your PC. Next run Track IR as administrator by right clicking on the icon and select 'Run as Administrator'. If you do not have administrator privileges, please contact your IT personnel.
