I've been having problems accessing the net through internet explorer(kept saying unavailable), so i've tried downloading version 7 from microsoft. Reason for needing IE is to get security updates for my pc cos it keeps trying to do it through IE but wouldn't let me connect through it for some reason. Anyway, now i've downloaded the new version, when I try to install it, it says " Setup could not verify the integrity of the file Update.inf. Make sure the Cryptographic service is running on this computer". Sorry for waffling on but what the hell does this mean? I'm totally lost and clueless as how to get IE running on my PC. Any help would be greatly appreciated.
