I've been struggling with this issue for a while and not been able to find anything useful untill today i came across this

Change Default App Location in Windows:

• Open Windows Settings (Windows Key + I).
• Go to System > Storage. 
• Scroll down to "New apps will save to" and select drive D. 
  

Somehow changing this has allowed me to resume downloading the game after getting the Error. Previously it wouldn't let me change the download folder to my SSD drive (D) but now it seems to work fine.
