Forget what I say below. That probably just started my game without the update. Resulting in being kicked for not having the anti cheat running. Will just start the full download again and hope there are no updates tomorrow so I can play than
Another day - Another update - Another failure.
But I might have found a workaround.
Not sure if all the steps are required, but here is what I did today
1. Got the message there is an update
2. Tried to cancel it
3. Update downloaded anyway and failed
4. Renamed the game folder
from C:\Program Files (x86)\Origin Games\STAR WARS Squadrons
to C:\Program Files (x86)\Origin Games\STAR WARS Squadrons2
5. Tried to start the game
6. Got a message game can't be found
7. Renamed the game folder back to the original name
8. Started the game. Game started to verify all files
9. After verification game tried to update
10. Update faile dwith that second message (something about corrupted files and repair)
11. Game started repairing itself
12. Game started
All in all took me around 5 minutes. Thats better than a 2 hour download I guess!! (and better that a 45 minute download too, hey I got fast internet :-)
