The programs are Adobe CS6 and Adobe CC on W10 v.1909. I uninstalled by using third party utility(Revo Uninstaller) and cleaned Adobe related registries.
The result is to my surprise they are all there intact except Acrobat. They all seems to be in working order. My plan was to uninstall CS6 and CC then reinstall CC.
How can I uninstall the Adobe CS6?
