Thank you for your response.
I installed Mono for wine through playonlinux, so yes i did install it into /home/user/.PlayOnLinux/wineprefix/ folder.
But that person who had the same problem did it as well and said that he needed dotnet20 and not mono20.

(if you can Crtl+F the name Alok on this page you will see exactly the same error as i have as well as him saying he needed dotnet20 and not mono20 in his last reply in order to make it work).
I am honestly a noob when it comes to mono or dotnet and i have no idea what is the difference but if they are different maybe i can try installing dotnet in PlayOnLinux environment and i was wondering if that is possible.
I appreciate you helping me.
