I'm trying to install window installer 4.5 but i'm getting an error reading "You do not have permission to update Windows XP. Please contact your system administrator". See short screencast to see issue.
I'm a domain admin and local admin and still can't get this to install. I can install applications but i'm guessing the issue is to do with update the XP OS.
If you need any more information please feel free to comment.
thanks!
