You could always go to the Control Panel and hit “system restore”. This will erase any programs that have been installed within the last month or so, returning your computer to the way it was before you installed that annoying doohickey.
This will show you the roles of each account on the system. If you are not listed as Administrator, have another account that is listed as Administrator login and change the role of your account. Then login to your account and retry the deletions.

Right click the program you wish to run. In the drop down menu you should see a selection “Run as Administrator.” Choose that selection.
My Win7 would not recognize me as administrator until I reinstalled Win7 and set myself up as administrator. Best Buy set up my computer in such a way that I would have to come back to them to do any administrator stuff. Usually when I get a new computer, the first thing I do is wipe and reinstall the OS. This time I was too lazy until it crashed.
