Ccleaner windows 7 start ccleaner broken

hello,

i have ccleaner (version 3.0) installeed on a windows 7 machine. when i click "start" then hoover over ccleaner then select "run ccleaner" under task, it brings up the uac warning just as it does any other time, but clicking "yes" does nothing but make a ccleaner icon appear quickly in the taskbar (next to the clock). it will not start the ccleaner program.

what is it trying (but failing) to do?? it will not open ccleaner. please help.

thanks!

"Run CCleaner" means "use the cleaner part silently". What you want is the "Open CCleaner" option. :)
