I have the exact same problem. When I launch Origin I get literally 10 Origin popups asking me what language I want to install something in. I had ME2 installed (plus dlc through BSN), but since of these popups I downloaded all the dlc again through Origin. However, pressing install didn't work. Fine, I thought, they're already installed since I downloaded them through BSN.
So I removed ME2 from my system, downloaded it again, installed it. Then I downloaded all the dlc through Origin too. But no, same problem. All dlc downloads, but the install button just flickers when pressed and nothing happens. Same in game details, the install button behind the dlc does nothing. But the Origin store correctly states what dlc I own:
- ME2 Digital Deluxe
- Aegis Pack
- Blood Dragon Armor
- Collector's Weapon and Armor
- Equalizer Pack
- Firepower Pack
- Incisor Sniper Rifle
- Kasumi - Stolen Memory
- Lair of the Shadow Broker
- Arrival
- Overlord Pack
When I try to start ME2 now, it shows a warning since "it's still busy downloading", while the download is at 100%. However, I can still play the game. After logging in in the menu I tried to load up my old save but there's another problem now: Apparently I have missing content! These can't be found:
- Normandy Crash Site
- Zaeed
- Firewalker Mission Pack
I think it's safe to assume the Cerberus weapons/armor and the Arc Projector aren't downloaded and/or installed either as they're all features of the Cerberus Network. Which, might I add, I have. I can see why my game says I don't have them, though: you didn't put them in the Origin store so I'll probably have to install them from BSN.
So yeah, please fix the popups every single time I open up Origin. It's ridiculous. And secondly; if you're going to add the dlc on Origin, do it right and don't leave out a few.
edit: Origin Version 9.0.15.65 - 198678
I now accepted all downloads and paused them right away so it's not a giant popup spam when I open Origin. As they just stay in the download list, it's an all right temporary solution. Everything is downloaded and installed through Origin, I didn't install BSN dlc. I'll just wait for a fix.
