Hi guys,  
i’m trying to build a Dedicated Server for my project, then i tried to follow this tutorial from official Wiki:

but actually i’m blocked to the 2nd step, because when i click on GenerateProjectFiles.bat, this is what happen:  
[http://prntscr.com/ekpn9m](http://prntscr.com/ekpn9m)

Honestly i already installed the right NET.Framework version, considering i have v3.5, 4.0, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1

I searched a lot of possible solutions, and realized that; maybe in some file there is not the directory to the correct NET.Framework version.  
Someone know how to change the directory of framework on source engine files?

thank you,  
Fabry
