Can't use Processor Affinity Tool on bsplayer.exe

[mistress_larisa]

I have an Athlon X2 processor. (dual core)
I want bsplayer.exe to run only on one core at a time.
I use imagecfg.exe http://www.robpol86.com/Pages/imagecfg.php
to do this, but after I set bsplayer.exe to run on uni-processor mode, when launched, bsp says:

"Integrity check failed! This file has been modified. Reason might be a possible virus infection."

So please, either do a better version which doesn't crash when run in multi-processor mode, or allow the bsp to recognize the bytes changed as not a virus behaviour.

I want to use this to permanently set bsp on one core, don't want to use task manager every time I run a movie or other lauchers or methods.
