Trouble starting RF2 for first time

[K3773R]

When I try to launch single player from the launcher, I get the RF2 splash screen for about 15 seconds, and then it kicks me back to the launcher. I've verified game files as instructed. Trace file is attached.

It seems in the trace file, as if the problem appears at the point when the shaders get loaded.
Maybe the problem is caused by the windows user rights, that the shaders can not be extracted.
Try this:
Start steam as usual.
Then go to the folder ..\Steam\steamapps\common\rFactor 2\Launcher
Rightclick on the file "Launch rFactor.exe" and select "run as administrator".
Does that help?

Bang: 9th line: 1.21s osman.cpp 1024: exe is 32-bit
Start the Launcher and make sure the Force 32-bit is not ticked.
rF2 or Steam shouldn't need to be run as admin
@K3773R what are your computer specs?

....rF2 or Steam shouldn't need to be run as admin....

But it can help to identify problems.
