Great news! We are now working on a fix to re-enable Win 7 ANT+ sensor support! Expect it in a patch coming next week!
In our previous update, we had to deprecate Win 7 Sensor support due to an overall upgrade to the game that conflicted with Win 7 ANT+ support. While we originally thought that there was, unfortunately, nothing that could be done to support ANT+ sensors with Windows 7, we have recently discovered a fix that will re-enable ANT+ support. We have implemented this fix today and will post the patch once we're done testing the build for any major bugs.
Sorry for the inconvenience and thanks for your patience!
