[Solved]Visual Studio 2013 Pro Can't compile .dll

Ah, I think I finally found someone with similar issues as me.
On my laptop everything is working as expected, but on my desktop I just can’t get it to compile. I do have extensions such as Xamarin installed on both my laptop and desktop.

I’ve been trying to get more info on this error - usually there’s always some info - but I couldn’t find -anything- about this one… this thread is literally the only search result I could get…

I might also go into formatting and upgrading Windows, but it would be nice to get this working anyways, as I don’t have much free time to perform the format and re-setup everything.
