Absolute RUBBISH. Do NOT use whatever "hack" Dragon Prince just proposed. I figured out the problem and the solution, none of which requires anything remotely close to fiddling with your registry like they keep saying. THE PROBLEM: The reality is, who doesn't have microsoft framework anymore, right? We all do, in fact most of us have all sorts of versions from v2.0, to v3.5, or even the latest and most appropriate v4.5.2 and right there lies the problem. MO requires the use of 3.5, but when you upgrade to 4.5.x, it automatically disables, for a multitude of reasons that I won't get into. Another reason some of you are having this problem is because on Windows 8, 3.5 comes pre-disabled (again, for some darn good reasons), so that's another culprit. Ultimately, MO only recognizes 3.5, and won't recognize anything higher. THE SOLUTION: No "hacks", no registry meddling, no installing or repairing, or reinstalling.. none of this rubbish. You just need to simply turn 3.5 back on. In Windows 7/8, search for "turn Windows features on or off", and simply turn 3.5 framwork back on, by checking the boxes. Done, the error goes away. Problem solved, please add this to the freaking official FAQ to MO, thanks.
