Don't use any program to use your mouse on windows with bootcamp.
I had bootcamp on my iMac but due space on disk was small (80gb) I had to erase it and then create a new one. At that moment I used "Magic Utilities" (free on windows that for 28 day you can use all the features that the mouse has, after that it only works as a regular mouse but without scrolling for example) a driver that makes your Magic Mouse 2 work on windows.
Now that I deleted my old bootcamp and created a new one (120gb) I didn't install the driver "Magic Utilities" and the mouse is working as if I were still working on Mac; even scrolling! which is wonderful!
here's the link of magic utilities page, here you can download it. Just choose the device you need https://magicutilities.net/download
