Is it possible to use Magic Mouse 2 scrolling with Windows 7 Pro 64 on Bootcamp 5.1?

Hello,

ive bought a Magic Mouse 2 and i'm trying to get it work with my Windows 7 pro 64 bit installed on bootcamp 5.1. It is already connected but scrolling doesnt work.

I tried new drivers but the problem still exists. Do i need a upgrade to Bootcamp 6 ? The iMac was bought in 2014.

If you need additional informations just ask!

Thanks!
