I have a similar problem.
I have purchased the 4 disk Deluxe Edition of Dragon Age Inquisition for PC. I have attempted to install it twice now. It launches Origin then when I click “continue” it goes from disk 1 through disk 4 and then just holds with no completion. The Origin screen displays Dragon Age Inquisition Digital Deluxe. I didn’t purchase this for download because I didn’t want to spend the time and bandwidth monitoring that big of a download. I have suspended my virus scanner, stopped any other programs from running, and checked the forums for similar issues with no success. I have DAO and DA2 still installed on my system, do I need to uninstall them? Any help would be appreciated. I’ve been looking forward to playing this game for a while now and this is very frustrating!
