So I've had this issue for a while.
Everytime I try to play online with the launcher when activating a mod through the Game Browser the error in the title appears.
Without any mods however it works perfectly fine.
The log mentions:
----- C&C:Online Launcher Start -----
Game: Red Alert 3
Red Alert 3 Install Path: F:\Origin\Command and Conquer Red Alert 3\Red Alert 3\
Started game with: ""F:\Origin\Command and Conquer Red Alert 3\Red Alert 3\RA3.exe" -ui"
Caught CREATE_PROCESS_DEBUG_EVENT from Red Alert 3. Detaching...
Found game.dat process. PID 8516
*** Starting CA public key patching routine ***
ERROR: CA public key differs from expected value. Not patching.
And I have tried everything I could find on the forum related to this problem - nothing works.
I have the game on Orgin and on Steam, though it is currently only installed on Origin.
And on both it causes the same error.
Is RA3 online generally not compatible with mods? It works on C&C3 with no issues, besides desyncs from time to time.
