The installer u re trying to use is corrupted or incomplete.This could be the result of a damaged disk,a failed download or a virus.It may be possible to skip this check using the /NCRC command line switch
I get this error for any installers and i am using windows 95. Havent had this problem untill now. This happened after a friend did some brousing on my PC so it could be due to any trojan that corrupts install.
Any advise will be appriciated. Thanking you in anticipation.
