i have a problem with my Blender on Windows 10 and hope you can help me.

So i use Blender for Building Objects like houses etc. . The objects have to be exported in directx (.x) format.

With my old Computer (Windows 7) it wasnt a Problem and worked without any Problems.

Now with my new Computer (Windows 10) and with the same Blender Version (2.69) the Button "Export directx (.x) " Is missing.

Do you have a solution for that?
