I cannot get Garmin Express to find my VivoActive on Windows 10.
When I look at my devices, it shows a Garmin USB GPS is connected, so Windows 10 thinks it has a valid device using drivers C:\windows\System32\Drivers\gmngen.sys and gmnusb.sys
I was finally able to add it by answering the question when it connected on USB whether to use the VivoActive as a Mass Storage device. Not my way of thinking, but it was then able to find the device. No where in the docs does it state to answer this way.
