CL12: MTA registry entries are missing

The official installer can recreate MTA’s installation entries.

The message

Registry entries are missing

Codes on this page: CL12

Steps

Try one step, then check whether the problem is still there. Follow any "only if" line before changing a setting.

  1. Close the launcher

    Exit MTA before repairing its installation.

  2. Run the current official installer

    Download MTA from its official site and install the client in the intended location. Use the installer rather than importing registry files.

  3. Start the installed copy

    Launch the installation you just repaired. If the warning remains, tell MTA support the exact message and whether the installer completed.

    Careful: Do not apply registry fixes copied from unrelated forum cases.

Still stuck? The Fix tool reads MTA's own log on your computer and points at the matching steps. Nothing is uploaded.
