How to remove the pieces left from Visual Studio so that another VS does not swear during installation that you first need to remove the first one?

Question

Windows

Such a story: I had VS 13 professional. Decided to try to install VS 13 community. The installer started swearing that I should uninstall professional first. I went into Programs and Features and clicked to uninstall it. I didn’t want to delete, I gave an error that I didn’t have enough rights to delete (despite the fact that the admin account and in general everything was always deleted normally).
Then he simply demolished the folder with VS, and, surprisingly, it did not help.
Somehow you need to now remove the entries in the registry or where else all this is recorded, or force the VS installer to ignore the presence of another studio.

Answer 1

must be uninstalled using utilities like geek uninstaller

Answer 2

Here you are in vain. From experience I tell you that it is much easier in this case to demolish the Windows and put it all over again.
The fact is that along with the studio come a number of dependencies. They are like ninjas: where and how they get up, where they are registered, no one knows

Answer 3

Try using regedit to rename the branch of the desired version:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\
might work. Then you will return it.

Answer 4

Himself an evil Pinocchio. Although judging by
everything was shit before that.
