Hi, That's what I did about a year ago, in order to remove Norton. I created an Administrator's account using the method you suggest, but even when I logged into the Administrator's account I was still unable to rename the folder.
I did find a solution, however, that seems to solve the problem, at least on my computer. I disabled the UAC (Control Panel, type UAC in the search box and uncheck the User Account Control) and then I was able to rename the folder. Once I'd renamed the folder, I activated the UAC again.
I don't know why I didn't come across this solution when I googled "unable to rename folder in Vista". Anyway, thanks for all your help, and at least now the problem is resolved.
The Nero tech support's info on how to fix the problem I'm having with Nero, didn't solve the problem with the software. So much for their ability to solve a problem.
