Visual Studio 2017 Broken and Cannot Uninstall or Repair [duplicate]

Answer 1

I opened the Visual Studio 2017 Installer, clicked in Modify and in the window that open, I just clicked in Modify again, without any changes. It worked for me, I'm using Visual Studio 2017 Enterprise.

Answer 2

Do not try this solution before trying others as the first step just deletes everything in the directory C:\Program Files (x86)\Microsoft Visual Studio\2017\

The only solution which worked for me was:

1. run C:\Program Files (x86)\Microsoft Visual Studio\Installer\resources\app\layout\InstallCleanup.exe -full

2. run C:\Program Files (x86)\Microsoft Visual Studio\Installer\vs_installer.exe with admin rights

3. click modify and add some option

Answer 3

Open the visual studio 2017 installer. If you press on the dots next to the modify and launch buttons you see an option to repair.

Answer 4

I had the same issue VS2017 ENTERPRISE VERSION 15.2 (26430.16) RELEASE I opened VS2015 which I also had installed and closed it. I was then able to open vs2017 without issue. VS2017 had worked for weeks without issue and no updates were applied in the interim so exactly what caused the problem is unclear.
