Why this is has us reaching back in time all the way to about DOS 2.0 when folders (subdirectories) were added.
Even today there is NO requirement that an app shall have an uninstaller. You can encounter apps that you just drop the app into it's folder and you are done. To remove you delete it. It's that simple.
Can really irk folk used to the newer way of dealing with apps.
I have a program on computer that doesn't have an uninstall listed. I downloaded the Revo uninstaller and it doesn't show it. I went to regedit and it's not there for whatever reason. It's a game and I can play it so why is it not listed anywhere. I want to uninstall it. What do I do?
