32-Bit editions of 7077 have the Themida bug.
64-Bit editions don't.
Just wait for a new build to leak.
Are you sure its not the game? i have yet to have any problems running any game on both 32bit and 64bit. That or let me know the name of the game and I'll post a video of it running on windows 7. Also let me know what you want me to use from build 7068, 7077, or 7106 and 32bit or 64bit.
