need administrative privileges

[tidbit]

I just tried installing ProfitUI reborn. I downloaded to winzip and tried to extract to the UI subfolder I created (as per the installation faq's) but installation failed. I got the message that I need administrative privileges to do this. How do I set my administrative privileges for downloading and installing the UI? Note that I have to run EQ2 as administrator, too (to start the game, I right click on the EQ2 icon and choose "run as administrator") in order to play. I have Windows Vista.

Thanks in advance for all your help!
