This is probably a ridiculously easy thing that I am missing, but I can't add the Mono runtimes to Xamarin.
I'm using Windows 7 (64-bit), and I've installed Mono to the default location.
I have found the menu under Options -> Projects -> .NET Runtimes, but I don't know which folder it wants me to select to add Mono.
I've tried "C:\Program Files (x86)\Mono" and a few folders under it, but I always get the error message "Mono runtime not found".
Any idea what I'm doing wrong?
