Error while Visual Studio Installation - Existing Installation broken - Not able to launch VS Installer.

Question

I am not able to use/install Visual Studio. When I try opening Visual Studio Installer, it displays the error “Sorry, something went wrong” and nothing happens. I was able to use the Visual Studio on my laptop seamlessly. While removing some temporary files yesterday, it seems, some “important” temp files were removed. And, I am not able to launch even the Visual Studio Installer now. I've tried the following steps already:

1. InstallCleanup.exe
2. Run following command for cleanup:
   1. DISM.exe /Online /Cleanup-image /Restorehealth
   2. sfc /scannow
3. Windows update.

But, nothing seems to be working and I am unable to use my Visual Studio. Request some help in getting this issue resolved.

Hello @Himanshu Shukla,

Welcome to Microsoft Q&A forum.

Do other applications run correctly on your machine except Visual Studio?

If the deleted temp files can be recovered, please recover them.

Please try to manually remove VS firstly. Remove following folders and Registry keys:

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

C:\Program Files\Microsoft Visual Studio

%programdata%\Microsoft\visualstudio\packages

%Temp%(you can just rename this folder, instead of removing it. A reboot may be needed)

C:\Users\username\AppData\Local\Microsoft\VisualStudio\17.0_XXXXXXXX

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\VisualStudio\Setup

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\Setup

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\Setup

After that, reboot your machine and download a new VS bootstrapper file then run it as administrator.

If manually removing Visual Studio doesn’t work, please reproduce this issue, download and run this collect.exe tool. Wait for several seconds, then navigate to %Temp%, find a file called vslogs.zip, extract files and open subfolder called Temp, check the files start with dd_installer and dd_setup. You can search for key word "error" and share us the detailed error code/message for further check.

Best Regards,

Tianyu
