Ladies and gets...i am hoping you may be albe to shed some light on this problem.
My Boss!!! got caught with the balster virus a few weeks back, he got hold hold of the fix and also the MS update on a floppy. His PC seemed to off taken the fix, but would not take the update from MS, he kept on getting as follows
"KB823980 set up error. Set up could not verify the integrity of the file update.inf Make sure the cryptographic service is running on this computer"
Now i have looked, and can find no "cryptographic" service on his PC....mainly because i am not as clever as you lot....
