I got this mouse to function on my new W7 work laptop. I recently got a Lenovo T440s at work and wanted a nice mouse to go along with this considerably more compact laptop.
Having done some research, I found that this device is a Bluetooth SMART or LE (Low Energy) device. This is what makes it slightly different than your standard mouse I believe. SMART or LE Bluetooth seems to be a fairly recent innovation. My laptop
discovered and paired with the mouse without any issues, however the mouse still did not function.
I downloaded Microsoft Mouse and Keyboard Center, hoping that it could possibly install some sort of file or driver that might wake it up to no avail.
I also played around in the "Devices and Printers" panel attempting to remove and re-add the device.
I finally noticed something in Devices and Printers. When you click on the paired, yet not working, mouse (comes up as "Arc Touch Mouse SE") an extra menu up top labelled "Bluetooth LE Services" clicking on it brings up the dialogue attached. Clicking
"Try Again" brings it to life.

It works as expected, scrolling with haptic feedback works etc. The only issue is that when I scroll it makes this old school audible scrolling sound along with the feedback which is kind of annoying. It's not something you can turn off without software.
The other issue I have found is that if you turn the mouse off and back on again, or if it goes to sleep on its own, it won't reconnect with the computer properly on it's own. You have to go back to devices and open up the "Bluetooth LE services" dialogue
again.
Considering this is a travel mouse, I think I will keep it for now in the capacity it does function. It's not ideal, but it's good enough.
That being said, this is proof positive that this device should have no issues working with any OS as long as the computer is capable of this new Bluetooth SMART/LE standard.
This worked perfectly for me with my crappy Dell laptop and Win7 x64 Pro.
Thanks again for the advice.
