If you are using the windows store app stop!
I had same problems and when I used a browser and went into the store via microsoft.com everything went smoothly.
Try using the link:
I hope this ends up working for you.
Thank you for trying. I had tried to do that (among a myriad of other efforts) for 8 hours a day for the past three days already (your link automatically takes me to a link that automatically opens the STORE I tried to avoid [I also tried the XBox app for PC]). The problem seems to be Microsoft are employing minority spastix to do part of organizing the coders. I have an XBox One X which uses the same e-mail as what I used to buy/install the game on PC, but as the Console does not allow this game to install (wrong model), it now seems to be not installing fully on my PC also because e-mail linked or some such (the install locks up after 10 or 20Gb of install (600Gb spare on the SSD [sometimes telling my my empty SSD is full]); But the Game used to work on this PC before all these recent updates the last month (where previously normal people likely used to do the coding).
I guess Microsoft are just trying to destroy the time of their customers in order to ensure we never buy anything from them ever again.
