Unity and Windows 10 Starting issues

I apologize if this one is already posted, I could not seem to find it anywhere

Original problem, installed Unity 5.4.0f3 (64 bit) and was able to start the program without issues and start a project. Trying to open Monodevelop from inside Unity5 gave a .NET Framework 4.0 error when I tried to open any C# script. I fiddled around with trying it by uninstalling all of the windows 10 .NET Frameworks (the 2.0, the 3.5, and all of the 4.5/4.6 series installs) then reinstalling them from the windows 10 features page. I also uninstalled all of my Visual Studio 2013 and 2015 files and reinstalled, but I get some errors while reinstalling even though it shows up in the program list as an installed software.

I made the problem worse by doing this, after reinstalling all the above programs, Unity 5.4.0f3 won’t open. It just gives the “microsoft circle orbit” for a few seconds, then nothing. “Unity Editor” appears in the task manager but no program seems to run. Trying to run monodevelop from the executable in the folder will do the same thing, but nothing appears in the programs running list. I also installed the standalone version of monodevelop, the xamarin studio software which has the same issue.

I’ve still got a version of Unity4 that runs fine, but can’t open any script in monodevelop since it won’t open from inside Unity4 either.

Any advice on where to go with this one? Could it be the visual studio not installing properly?

Thank you.

Just an update, since I’ve been working on it for the past couple hours

I uninstalled Unity 5 64 bit and installed Unity5 32 bit. The same problems occurred. I was unable to open Unity 5 from the desktop shortcut icon using administrator mode.

I opened the Program Files/Unity/Editor folder and ran the executable file itself from the folder in admin mode, and the Unity5 software does the error describes above, but then starts after about 3 or 4 minutes.

Finally, if I open the Program Files/Unity/MonoDevelop folder and run the shortcut in for Monodevelop in administrator mode, the error above occurs and nothing opens, but if I go to the Program Files/Unity/MonoDevelop/bin and run MonoDevelop.exe, it opens Unity5 as well, but not the monodevelop software…

That is bizarre…
