UnableToStart

From BeamNG

The launcher was not able to locate the game's executable. Please reinstall the game.

The launcher was not able to launch the game because it needed administrator rights.

Got to the games folder and open the folder /bin64/.

Right click on the game executable "BeamNG.drive.x64.exe" and click on Properties

In the "compatibility" tab untick the highlighted line.

It's not recommended to run the game in administrative mode.

If you are obliged to do so, you need to apply the same mode to the launcher executable.
