Downloaded a certain app on Ipad, Android phone, but cannot get it on Windows machines. Yes, it is indeed available to run on "all devices" and "all but the oldest Windows". I cannot access the Store on Win 8.1 Pro laptop at all anyore. When I try to download this particular app on Win 7 Pro desktop, the app does show up but there's no indication whatsoever how to download it. I finally was able to get onto Windows store on 8.1 Pro machine - after days of it not even coming up. Now it keeps saying that download can't be completed because Internet connection is too slow. I download the same exact app on an Ipad, and an Android phone wirelessly on this same Internet connection. I even hardwired my laptop with a DSL connection and it still 'won't complete'.
