Magic mouse on bootcamp with cad files

Hey,

I want to know if can someone help me to figure out my problem.

I am student to architecture and need the middle button for cad files like autocad, sketchup etc...

For mac I have the magicprefs app - that enable the middle button.
but for windows (run with bootcamp with the 5.1 driver) I don׳t see any solution for this. (and a lot of topic with this problem).

I happy to see answer from you.
thank you very much.
