Installing IC after attempted failed installation fails again cause its already installed?

I attempted to install v 10 on my new Dell. Installation failed because c++ 2017 redistributable was not installed. I installed c++ 2017 redistributable. the installation then failed because it said that intellicad was already installed and I had to remove it before installing . I cannot find Intellicad installed anywhere or anything referring to CMS. I went though installed programs and could not find anything, Any suggestions would be appreciated.
