James,

My name is Aron Semle. I'm a Solutions Manager for the apps. Although Windows 10 isn't officially supported by the platform, you're the second customer within a week after the 8.1 release to request this. We'll be adding support by the next release the latest, and we'll let you know if we have something sooner. In the meantime if you have Windows 7, it will work on that.

Sorry for the inconvenience, and thank you for your feedback!

- Aron
