saying: Setup could not verify the integrity of the file Update.inf. Make
sure the Cryptographic service is running on this computer

SP2 won't install for me, can someone please help, thank you.

Go to Control Panel, Administrative Tools, Services. Double click on
Cryptographic Services and Start the service. Then try to do the install.
