Help, please. Brand new to the forums and to Vista. Installed Home Premium upgrade to a Sony VAIO AR250G. Run as administrator appears on my right click menus, but when I try to use it, I still get "You must be logged in as an administrator when installing this program." I noticed that the little Windows shield icon by the run as administrator icon is grayed out.

I've used the search function here, and the MS Knowledgebase and I don't see an answer to this problem yet.

Please help!
