I'm trying to install an update for .NET4 on a Windows 2008 box and I keep getting the error #80200053. All the other updates installed fine but this one refuses to install. I've tried it three times with no luck. I don't believe it is a virus or anti-virus software because the machine is a clean install currently without anti-virus software installed. I've tring it with the firewall disabled and I still get the error. Does anybody have any ideas?
