So I decided to upgrade my work comuter from IE6 to IE7. This update was not in the Windows Update menu anymore so I went to microsoft.com and downloaded the installer. When I go to run it I get this message: I went into IE6 and removed Microsft from the Untrusted Publishers list as the link on the bottom of the message suggests. I then restarted the computer and tried again. Same message. So I then installed the cert by clicking the link that says "Microsoft Corporation." Restarted computer and same message... any more ideas?
