How to uninstall visual studio 2022 and all its components when I couldn't open the Installer?

Hello @Cappi Lau ,

Welcome to Microsoft Q&A forum.

If all above don’t work, you may consider trying to remove VS manually.

Remove following folders and Registry if they exist(please back up them before removing):

For folders:

C:\Program Files (x86)\Microsoft Visual Studio

C:\Program Files\Microsoft Visual Studio

%programdata%\Microsoft\visualstudio\packages

For Registry Keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\VisualStudio\Setup

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\Setup

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\Setup

For cache files/folders:

C:\Users\username\AppData\Local\Microsoft\VisualStudio\17.0_xxxxxxxx\ComponentModelCache

%temp%(you may need to reboot your machine before removing/renaming the Temp folder)

If you installed some other program/extensions separately, you can also try to uninstall them from Control Panel.

BTW, currently, you can’t install everything of Visual Studio to another drive. Some parts of VS need to be installed in C drive, so you may keep enough space in your C drive(Install everything of VS on another drive).

Sincerely,

Tianyu

Try to use the Control Panel (using Search feature of Windows). It includes the “Uninstall a program”. Find the Visual Studio and Visual Studio Installer in the list.
