Recently I have faced this issue. I tried to install the Visual Studio community edition. Cannot start Visual Studio Community Edition after installing. Got the error message "The setup for this installation of Visual Studio is not complete. Please run the Visual Studio Installer again to correct the issue." when launching.
Tried to reinstall, repair, cleanup of install, deleting old directories. Nothing works. Here is the workaround which fixed.
Workaround:
- Close any active Visual Studio applications
- Go to the path C:\\Program Files (x86)\\Microsoft Visual Studio\\
- Delete Installer folder
- Now start the Visual Studio. It works :)
