I've found a way to play on the C&C: online server with the C&C: The Ultimate collection version  of Kane's wrath. 

Follow these steps:

1. Download the CNC fixed launchers.

• Launch the .rar file with 7zip or any program that can open .rar files.

      2. Launch the CNC fixed launchers & make sure it checks C&C 3: Tiberium wars & Kane's Wrath.

      3. Read the readme.text to make sure you follow each instruction carefully.

• make sure you disable Origin in-game for this to work.

      4. Launch C&C: online  Launcher 

      5. After you launch the C&C: online launcher, you go to your origin version of the game & press play.

      6. After you press play, launch Kane's wrath on the C&C: online launcher.

      7. The game Will launch, & enter everything in the login with your information for C&C: online Server.

      8. there you go! have fun playing some Kane's Wrath on the ultimate collection's version!

I hope this will help people who have the ultimate collection version of the game to experience multiplayer with C&C: online !
