Black screen issue again

[NeoToriyama]

It's the same problem many people seem to be having with IMU emulation in SteamVR. After a few minutes, the screen goes black and creates an unfortunate disappointment. The only solution was to create an environment variable to disable the 64 bit version of SteamVR. Can someone make a tutorial on how to do so? I'm able to create an environment variable, but what folder/and or file do I target? Any help would be appreciated.
