So far I have only checked on the site of the processor company, Atmel.com, their is a lot of information and the general impression is that it works on Windows 7 with latest service pack, unfortunately we used Windows 7 here until this year and had to upgrade to 10 for the latest UPS program so I have no way to test. I have written the factory, but I suspect the issue is either 32 bit vs 64bit or an update and it should work.
