Troubleshooting OpenUA Metropolis Dawn expansion (Windows 11)

    Hi all, basically explains everything in the title.

    UA_source.exe is working great, not bugs or issues whatsoever, however the ghorkov and taerkasten files briefly start to open, close immediately without a noticeable program open, then the file disappears from the folder. Anyone else had similar issues and managed to work around it? Or maybe you can direct me to the forum page with the answer.

    Thanks in advance :grinning_face:

    Hello tgbuckley482, welcome to the forums!

    Firstly, am I correct in assuming that you have acquired the latest OpenUA Standalone Package (version build 2025-03-09) from our verified sources here, and currently attempting to launch the Metropolis Dawn expansion campaigns using the batch files provided directly inside the package itself?

    The custom batch files that are designed to launch the Metropolis Dawn expansion campaigns inside the OpenUA Standalone Package are technically substitutes for the official Metropolis Dawn shortcuts, which are automatically generated when MD is installed via using the official Metropolis Dawn installer file, but for UA_source.exe instead Ua_xp.exe in order to launch the game via OpenUA engine. Their locations should not be changed either.

    Normally these batch files should work without any issues regardless of Windows versions (they have been tested extensively already before). In fact, this is the first time an issue like this was reported. From your descriptions here however, it appears the command lines are not working as intended.

    Since there is no precedent information available, we will have to apply some general trial-and-error approaches and methods to resolve this case.
    Please try the following options (in no particular order):

    ---

    • Launch the batch files with elevated privileges (Right-click -> 'Run as administrator').

    • Rename the batch files extension from .bat to .cmd and try launching them again.

    • Launch the batch files from the command prompt (CMD.exe) directly inside the game's root folder.

    • Move the location of the OpenUA Standalone Package folder to somewhere else, especially into a directory that is not protected by UAC settings.

    • Create two shortcuts of UA_source.exe manually inside the game folder, right-click on them and open their Properties tabs, and then add each of the following environment option arguments at the end of their Target fields:

      -env Ghor_env
      -env Taer_env

      So the following results in Target fields of each shortcut will look like:

      ...\UA_source.exe" -env Ghor_env
      ...\UA_source.exe" -env Taer_env

      Save both changes and try launching these new shortcut files.

    Please report back in this thread if none of the above methods worked for you.
