MonoDevelop wont open in Unity3D 3.5.2f2

Hello there!

I’m using Windows 7 64bits and just installed Unity3D v3.5.2f2 (free). But when i’m following some tutorials on internet, I saw many ppls using MonoDevelop integrated with Unity3D, but when I do a double click on a C# Script, nothing happens!

I checked already the preferences and it is set to MonoDevelop (build-in).

I have dotnet 4.0 instaled on my sistem…

Any clue?

Thx for attention,

Afonso Lage.

Solved after install 3.5.2f2 on top of 3.4.1, like Sarpet said.
