Ahh, sorry : )
Forgot to link it ^^
It's not for sure that you don't have framework.net, you should try it in order to comfirm it. Run it as administrator could work aswell. If it still doesn't work, you could download the framework.
Framework.net is something Microsoft forgot to make standard in their OS, still some computers has it.
