Hello, I have a Dell Inspiron E1405, and I am running Windows Vista Home Premium. I am trying to find out how to uninstall an old downloaded demo version (40-day trial version) of WinZip. I go to the control panel and click on "uninstall programs" and when I try to uninstall WinZip, it says that the Administrator has prevented me from such actions. I am the administrator! I have already run into this a few times in other areas, and there is usually a simple solution, but this time I couldn't figure it out on my own. Please Help!!! I also am not very technically inclined, so please be as detailed and simple as possible.
