@David.Sullins I already did this before, using the “Advanced System Settings” option. When I go to the “Environment Variables” window “DOTNET_ROOT” is nowhere to be found (it isn’t listed when using the PowerShell method either). If I create a new environment variable, name it “DOTNET_ROOT” and then set it’s value to the path you mentioned earlier nothing happens. Absolutely no difference, still can’t package my Windows projects.
Can you show me your “Enviroment Variables” window (or a list of your environment variables)? It’s very strange that “DOTNET_ROOT” doesn’t exist for me.
