The program downloads and installs w/o a problem.
I unchecked the "Check for automatic updates" and still the nothing.
No, CCleaner does not show up in the 'Add & Remove Programs' window. It does show up on the start menu and in the all programs list.
The program loads & installs normally, but when I click on the the icon to open & run the program I get the hourglass icon for about a sec or two and then nothing.
Not sure what yo mean by Safe mode?
