Tried installing Desktop version on Linux mint 18

I tried installing Desktop on Linux mint 18 (should be the same as Ubuntu 16.04). The installation went ok, but nothing happens when I click on the icon in the menu. I can’t figure out what’s wrong.

There have been several threads indicating the need to update Mono. For example, this one might be helpful:

OK, it works now. Thanks for the really fast reply!
Very interesting program!
