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

Question

I am having an issue with starting Visual Studio 2017 Enterprise and I cannot report a problem to Microsoft's Developer Commnuity because it requires running Visual Studio 2017. Crap!

I was updating VS 2017 with an update from this week and during this my PC crashed and I had to reboot it.

Now when I start VS 2017 I get the following message:

The setup for this installation of Visual Studio is not complete. Please run the Visual Studio Installer again to correct the issue.

I ran the installer and it didn't detect any version installed.

I tried some commands from the VS community like:

%programfiles(x86)%\Microsoft Visual Studio\Installer\resources\app\layout\InstallCleanup.exe -full 

This command cleaned some stuff, but the result was the same. I cannot remove the corrupted installation.

I also can't install any other VS 2017 edition - I get the following error:

[4068:000d][2017-04-12T20:13:20] Error 0x80004003:    at Microsoft.VisualStudio.Setup.Cache.InstanceRepository.GetInstance()    at Microsoft.VisualStudio.Setup.Cache.CacheRepository.<GetInstances>d__27.MoveNext()    at System.Linq.Enumerable.FirstOrDefault[TSource](IEnumerable`1 source, Func`2 predicate)    at Microsoft.VisualStudio.Setup.Engine.VerifyInstallationPath(IServiceProvider services, String installationPath, IInstance instance, IQuery query)    at Microsoft.VisualStudio.Setup.Engine.Install(Product product, String destination, CancellationToken token)Object reference not set to an instance of an object. 

I'm now stuck with a broken Visual Studio 2017, which doesn't run and I can't post to the community, because this is done through Visual Studio 2017.

Can anyone suggest a workaround for this?

Thanks!

I managed to find a fix for this issue in this post: Error 0x80004003 during VS 2017 RC install

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.
