News: Incompatible Client Version Fix

Download Fix for “Incompatible Client Version” Error

Many new users have encountered an issue with cached patch information when trying to play The Matrix Online. The symptoms of this problem are that The Matrix Online game client does not recognize that there is a new version of the game, but when you try to log in, you are told that you have an "Incompatible Client Version".

The cause of this issue is ISP side caching of the patch files. Our patch system includes a no-cache header to prevent this from happening, but some ISPs ignore this parameter. As a result, users on these ISPs will not be able to patch to a new version in a timely fashion, preventing them from playing the game.

Our developers have devised a workaround for this problem, which will be integrated in to the game in a future version. For now, users affected by this problem will need to download a special patch file (See Below).

To use this file, please follow these instructions:

  1. Rename the current version of patchctl.dll in the p_dlls subdirectory of the main client directory to save it (or copy it somewhere for safekeeping).
  2. Unzip the patchctl.dll in the attached zip file into the p_dlls subdirectory.
  3. Run the launcher.
  4. If the launcher restarts, close it after it restarts, and repeat steps 2-3.


If you are still encountering problems with your game client not patching after this process, please file a petition with Tech Support, and include your patchctl.log file so we can help diagnose your problem.
