As an update, I did finally get around to doing the update to windows 10 version 1809 and that did resolve my issue. I had the "stuck at 81%" issue and had to create a USB drive with the windows install tool. As soon as I went back to the windows store, the Install button was blue and allowed me to install on PC. Thanks @Wyvyrias and @Blind Io
I purchased this play anywhere title on the xbox store. the MS store shows that I own it, but the install button is greyed out. I have already updated and reset the windows store app and am current on windows updates. I was able to install on the Xbox One.
