Whenever I try to use a file that I've downloaded off of LimeWire in a .zip format, I get this:
! Cannot execute "C:\Users\UserA\AppData\Local\Temp\Rar$EX00.949\Se tup.exe"

I am using Windows Vista, WinRAR 3.71 (corporate edition), and I am on a broadband connection. I do have a firewall, but it is set at minimum and I have allowed all permissions to LimeWire for uploads, downloads, and internet connection.

Thanks for the help, if you can help me.
