* The solution, in a nutshell, is to disable your firewall. If you’re using McAfee Personal Firewall Plus, F-Secure Internet Security, Norton Internet Security or another Firewall vendor, see its respective support page for assistance in disabling it (temporarily). If you’re using the built-in Vista Firewall, keep reading.

* Open the Control Panel and select Security.

* Select Turn Windows Firewall on or off.

* Select Off (not recommended), click Apply and then OK.

* Back at the Windows Update screen, click the Try again button.

* The download(s) and installation should start…

* and this time successfully install. If a restart is required, make sure to re-enable your Firewall once your PC restarts.

* Though this solution will work for most Vista Update errors
