Visual Studio References Unavailable + error, what's going on?

[Gemviper]

This is probably a silly mistake on my part but the solution isn't jumping out at me.

- Visual Studio 2017
- .Net Framework 4.6.1 IS installed
- Project tells me that 4.6.1 is NOT installed on this machine but I can switch from 4.6.1 to 4.6.1 (not a typo, it's offering a switch from and to the same version
- None of the references are being found


What am I doing wrong?

Is this a new computer build?  You might need to install the developers packs for .NET?

Yes, it's a new setup, but it has the same settings that I've used in the past as best I can tell. I've quadruple checked, 4.6.1 is installed and working properly but the project says it's not, even if it's using it. If I use the switch option none of the extensions can be found. If I try to use the instal option is gets to 4% and quits saying It's done(because 4.6.1 is already installed).
