I was unable to install visual studio express 2012 on a fresh laptop running windows 8.1 when I used the downloadable installer. There was a conflict with compatability settings that would not let the install go through. I was finally able to install visual studio express 2012 by downloading and mouting the ISO installer. The installer hung during the finalization, but it was far along enough and was successfully installed.
All drivers are in place. I have not yet actually plugged the Plus 2 in because I don't have a cable, but otherwise I am ready to go!
