Uninstall issues (CC 2014; CS5) & Creative Cloud Cleaner Tool questions

I am trying to uninstall old versions of the CC apps (2014) as well as CS5.

The standalone uninstallers do not work, they all give me a generic error (reboot, etc).

None of these apps show up in the Creative Cloud Desktop app. I know in the past they did, even after my subscription ended.

I have gone through reinstalling CC Desktop, renaming the OOBE folder, etc.

I am concerned about the CC Cleanup Tool, the information is vague about what it does. I want to make sure I am not going to screw anything up with my CS6 installed apps. It seems the only option to "cleanup" CC and CS5 is to include CS6 in the cleanup.

Since I am not sure what the "cleanup" does I am hesitant to run it. It seems to cleanup installer logs/info from what I can tell, but not sure if that means it will wipe out installation info for apps I want to keep -- like CS6.

Can anyone verify that running the cleaner app will not affect my CS6 installations?

I just want to uninstall all the old apps from my hard drive and leave CS6 intact. The online help indicates that I need to do this with either the standalone installers (which do not work) or the CC Desktop app (which does not list any apps as installed, except Acrobat DC which I never installed to my knowledge).

Thank you.
