--- Comment #4 from Contex contexmoh+winehq@gmail.com --- Created attachment 67080 --> https://bugs.winehq.org/attachment.cgi?id=67080 Origin Mass Effect 2 game filenames
Quick note:
I was able to manually download the file Origin was attempting to download without any issues (via the authed link in the Client_Log.txt):
--- -rw-rw-r-- 1 me me 17G sep. 24 2019 mass_effect_2pcpatch__wwrun_2__103_origin_rtp319aabff8a244bdd91cf8e2ea54517ff.zip ---
Interestingly enough, I believe this zip might contain the whole game and all the files needed to actually run the game, see the attachment.
This might be a dirty workaround, download and extract everything manually (DLCs should work the same way), and let Origin find the game(s)? I will have to do some more testing tomorrow.
