How to Use the Thaluna Diagnostic Build

The full Thaluna download includes Thaluna.exe and Thaluna-Diagnostic.exe in the same folder. Use the diagnostic executable when you need a visible console for startup, OCR, GPU, or provider problems.

1. Use the included executable

Open the extracted full-version folder and run Thaluna-Diagnostic.exe. You no longer need a separate diagnostic download or channel.

2. Reproduce the problem

The diagnostic executable opens the same application with a console window that shows startup, OCR, translation, TTS, and provider output.

3. Copy the output

After the issue happens, click the console window, press Ctrl + A, then press Enter. Paste the output into your forum post.

4. Include system details

Attach the console output, your CPU, GPU, Windows version, selected OCR/translation backend, and a short explanation of what you were doing.

Normal executable logs

Thaluna.exe runs without a console and saves rotating diagnostic logs locally in %LOCALAPPDATA%\Thaluna\logs. The diagnostic executable is still preferable when a startup failure prevents you from locating the newest file.

Mandatory for crash reports

For crashes or OCR failures in the full version, reproduce the issue with Thaluna-Diagnostic.exe before posting. Bug reports without console output or the newest local log may be too ambiguous to diagnose.
