Hello everyone hope you can help. I tried updating a friends computer yesterday, i have both versions of windows 7 32 and 64 bit. I was not sure what version he needed so i tried 32 bit first and got this message The error message says " The version of this file is not compatible with the version of Windows you're running." I know its Win 7 ULT because it has the serial number on the actual case. I finally saw it was 64 bit in small font also on the case i tried installing 64 bit of Win 7 ULT but i got the same error message, im formating before i install any version am i doing anything wrong i cant seem to get it working unless its the video card thats not letting me install this version, this PC was running windows 7 before my friend got a virus thats why i was there.
