This is a continuation of several problems I have been going through over a major failure of my computer that had XP and now Vista. I tried to install SHIII and it took forever, so I imagine it is installed and yet when I try and run it, I get a message that says: ERROR: to install this application, you must have administration rights on your computer. As far as I know, I do as I have no problems installing any other programs. Any suggestions on how to fix this?
