Damn, I thought the ANT+ was plug and play. Are you running Windows 10 ?
I put Windows 10 on everything I owned a few years back and shit just plugs and plays.
Download Windows 10 from Microsoft and buy a $4.50 key (they've put the price up, used to be $3).
This will give you full Windows 10 Professional.
I did load it onto an old laptop and it basically killed it. The laptop was too old to run 10 and it takes too long to load and process stuff now.
