Patcher Issues

Patcher doesn't start - incompatible software error

If you have a 32bit Operating System the Patcher will not run.
You can download a 32bit-Version of the Patcher and put it into your game folder: Muh Patcher 32bit

Patcher doesn't start / no error message

If you have your Muh Patcher pinned on the Windows Task Bar it doesn't show the popup when there's a Patcher Update available.
You could simply try to hit enter. If that doesn't work proceed here:
Note: it starts and hangs as a process which has to be killed via Task Manager
After that start it once through a classic link (e.g. on your desktop) or directly from game folder and proceed with the update.

Patcher Update doesn't work, menu repeats itself

Check if you're having a hanging Muh_Patcher process. Kill it via Task Manager.
You can also update the patcher manually by downloading it here: Muh Patcher
Save this file into your game folder.
