Did an install of programs - program installer did not register with Windows Installer consequently couldn't uninstall.
Manually deleted the folder and contained files.
Installed updated version of program and this version registered with windows installer.
Did an Uninstall and again, programs were not removed.
Ran CCleaner to fix install issues in registry but that didn't solve problem.
Manually deleted folder and ran CCleaner again -
Did good install and uninstall again and files still persist.
Somewhere those orphan install files persist in registry.
Any ideas as to how to remove them?
