How can I uninstall CCleaner?
It does not show under control panel - add/remove programs nor does it show in windows installer cleanup?

Try start - all programs - CCleaner -uninstall CCleaner.

Hello, and welcome to the forum.

If you downloaded the portable version .zip of CCleaner, you won't find an uninstaller.

I can't imagine a computer without CCleaner.

CCleaner Rocks!!!

If its not listed in Add/remove then you have probably used CCleaner to delete to caption. Have a look in CCleaner folder there should be uninst.exe that will uninstall it for you.
