Visual Studio Extension fails to install because of Microsoft.Net.Core.SDK

[vrapp]

I'm trying to install Visual Studio Extension, and it fails, looks like because "Microsoft.Net.Core.SDK.2.1 failed to install" because "Another version of this product is already installed" . I have installed Microsoft .NET Core SDK 2.1.526 (x64). I attached the log.

My first suggestion is to try installing the VS installer using a command prompt.

1) Start an Admin Command Prompt
2) Look for a Visual Studio program named VSIXInstaller.exe. For example, the binary file would be in something like, "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\VSIXInstaller.exe" - each system may vary and this is just an example.
3) Once you find it, execute the command:
"<path_from_above>\VSIXInstaller.exe" /a /sp "path\to\Vault\VisualStudioExtension_*.vsix"

If this doesn't help, it may require a re-installation of Visual Studio. Knowing the version of your operating system would be helpful as well.

Thanks,

The way I see it, it's not because there's some lack of permissions, but because there's another version of the product that is already installed, and this version is not an upgrade of it. This is very well known message from Windows Installer, when new installation has the same upgrade code, different product code, but not an upgrade.

Hello again,

The instructions I provided you with has previously resolved the error for other Vault users. It's definitely worth a try.

Thanks,
