Ntune Freeeze

I would really like to monitor my gpu temps while I overclock so I dl'd ntune. It installs fine, but when I click on nvidia control panel it locks up my comp. Any suggestions. Im running vista64

ok sorry for double post, but now all I want to do is remove it from my comp. I try to uninstall and I get this message...
EDIT....ok so i dl'd windows installer cleanup utility and I think it removed it. BUt regardless I still want to see some freakin temps lol
