Hi I am just the biggner for Unity . I have the latest version of Unity.
Mono develop show this error when I try to open it from Uniity and also for the it .exe file which is located on “E:\Unity\MonoDevelop\MonoDevelop.lnk”.
I even have installed seperate Mono Develop from the officail site of Mono Develop.Then also it shows the same error.

I am using win7x64 and my system information is below-

Plese provide me solution as soon as possible.

I got the same problem, i solved it by downloading the Gtk# for Net. from here:
http://www.mono-project.com/download/#download-win

after that i started it and chosse the option remove Gtk# from PC
then i run it again and installed it normally after that monoDevelop started normal again

Hope that helps you.

Fix here !

First of install the latest versiom of .net from the official microsoft website.
Then install it and rerun Unity.
It will surely work.

First of all Uninstall GTK# & Unity form your PC , then install the unity again.

It works for me. I am using Windows 10 (64 bit).

I absolutely agree!

Thank you very much, only this worked for me!
This is a correct answer.
