The Flash Programmer product page states:-
"SmartRF Flash Programmer and SmartRF Flash Programmer 2 run on 32 and 64-bit versions of Microsoft® Windows 7 and Windows 8."
Are you intending to support Flash Programmer 2 on Windows 10? Perhaps it should "just work"?
When I tried it it did not recognise attached devices. Screen shot attached.
