Can't reinstall .Net Core SDK after removal "product is already installed"

I uninstalled .Net Core SDK with "programs and features". When I now try to install the .Net Core SDK again, I get following Error Code:

Error 0x80070666: Process returned error: 0x666

Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel.

Solution

  • Assuming you are on Windows, Can you go to 

    C:\Program Files\dotnet\sdk

    Manually remove the SDK you are looking to reinstall.
