CTM uninstall

Could not remember password. Uninstalled CTM. Tried to reinstall CTM. Got message that CTM was already installed. Cannot find any CTM exe or other CTM file. How do I completely uninstall CTM?

Pls. do some reading in the forums first before asking a question !

I did read. Nothing in those articles help me.

For problems with Windows installer you can use Windows Installer Clean Up utility. This tool cleans up all Windows installer related traces from your computer. It will allow you to run an (un)installer where it was getting blocked because it couldn’t find a needed file or says the products is already installed.

This tool does not uninstall a program.
