If you look in the IDE log file, which is in the directory %AppData%\Local\Xamarin-Studio-6.0\Logs, and you see an error similar to:
System.DllNotFoundException: Unable to load DLL 'libglib-2.0-0.dll': The specified module could not be found.
Then you can fix this by installing an older version of GTK #. To do this, follow these steps:
- Stop Xamarin Studio.
- Delete GTK #.
- Install an older version of GTK #, for example GTK # 2.12.30
