LMU Trainer

Download the client for Windows

One file, no installer. Download it, double-click it, and the app unpacks itself into your user folder and starts. Nothing is installed system-wide and no administrator rights are needed.

No client build has been published on this server yet.

First run

1. Windows will show “Windows protected your PC” because the file is not signed with a paid certificate. Click More info, then Run anyway.
2. Unpacking takes a few seconds the first time. Later starts are instant.
3. In Le Mans Ultimate, open Settings → Gameplay and turn on Enable Plugins, then head out on track.
4. To send your laps here, open Settings in the app, enter this server's address, log in and turn on sharing.

The app needs the Microsoft Edge WebView2 Runtime, which is already part of Windows 11 and most Windows 10 installations. If it is missing, the app says so and links to Microsoft's free download.

Where your data lives

Recordings, best laps and your login are stored in %LOCALAPPDATA%\LMU Trainer\data and stay there when the app updates. Nothing is sent to this server unless you log in and turn on sharing. To remove the app completely, delete %LOCALAPPDATA%\LMU Trainer.
