Win. 8.1 64bit desktop. I am trying to download the RemindMe appointment reminder app from the Miicrosoft Store for use on my desktop. I sign in to my MS account on my desktop using my Skype details, MS sends me the code via email as advised, and I input the code. But then I get the message "It looks like you donít have any applicable device(s) linked to your Microsoft account. To install, sign in on a device with your Microsoft account" The Install Now option is greyed out and I can only click on Cancel.

I only use one pc, my desktop, I do not have any other devices. Can someone tell me what is going on please ? TIA for any help or advice.
