HELP ME PLS

[hipnotisanopile]

Hi guys,
can someone tell me, what i need to download or something else for this:
 "The version of this file is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher."

Thanks

For which program/file this appears ?

Btw if you installed OS w7 or xp x86 (32 bit) on your computer you must install programs for that version , not 64 bit .
