Cannot update WoW

I recently renewed my subscription for 6 months, and I’ve had this problem since I came back…about 2 months maybe. On my desktop, I cannot download or update WoW. I have tried deleting everything Blizz related and redownloading the Battle.Net app, but no matter what I do, I can’t get WoW to update. I WAS able to download everything onto a USB drive using a laptop, and also using the laptop for updates, but I no longer have the laptop, so that’s not an option.

I have no other Blizzard games downloaded, but it will pause and say “Waiting on another update”

I even tried doing a repair, but it only went to 1%…then back to 0% and “Waiting on another update.”
