I've been having some annoying troubles with RA3 when trying to Co-op campaign with my friend, But the game crashes immediately on launch unless disconnected from internet and CnC launcher freezes instantly when you try to launch it.
I've tried the following.
-Disabled my firewall
-UPNP off and on
-Running Steam, RA3 and CnC online in admin mode
-Tried this solution
- Solution: Open the C&C:Online launcher and use the Hook menu to hook your game. Then launch the game using the shortcut Steam made for it on your desktop (if you don't have a shortcut, go into Steam and make one). The launcher should pop up, so select your game and off you go. When Hooking, you should receive a prompt asking for your confirmation, this is how you know it worked. If you don't receive anything and the issue still occurs, check your anti-virus (Norton especially) as they are known to delete the hooking file. Add an exception for C&C:Online. (Note i'm not using any other virus protection software other then windows defender which i believe i have disabled, also "Allow an app through firewall" doesn't list CnC online for some reason)
-Tried running CnC in compatibility mode for windows XP
-Used Powershell -
(Here are the results -
Test-NetConnection peerchat.server.cnc-online.net -port 6667
ComputerName : peerchat.server.cnc-online.net
