Provide FastLogger file for troubleshooting in Archicad

Issue description

Technical Support may ask you to provide your FastLogger folder to investigate performance issues, crashes, or unexpected behavior in Archicad.

Solution

Before collecting the logs, note that the FastLogger folder stores recent diagnostic data and is limited in size (up to ~100 MB). If the issue occurred earlier and you continued working in Archicad, the relevant data may no longer be available, and reproducing the issue is often necessary to capture relevant logs.

First, Locate the FastLogger folder:

Windows: C:\Users\<username>\Graphisoft\Archicad Log Folder\<Archicad version>\FastLogger

macOS: /Users/<username>/Library/Logs/Graphisoft/Archicad Log Folder/<Archicad version>/FastLogger

• On macOs the Library folder is hidden by default. To access it see this guide.

Then, choose the option that best matches your situation:

Option 1: Issue cannot be reproduced

1. Close all Archicad instances.
2. Navigate to the FastLogger folder.
3. Copy the entire FastLogger folder to a safe location.
4. Compress the folder into a .zip file.
5. Attach the file to your support case or upload it as instructed.

Option 2: Issue can be reproduced or occurred earlier

Follow these steps to create a more complete and relevant set of logs:

1. Close all Archicad instances.
2. Navigate to the FastLogger folder.
3. Copy the existing FastLogger folder (old logs) to a safe location.
4. Delete all files from the original FastLogger folder.
5. Open Archicad and reproduce the issue.
6. Close all Archicad instances.
7. Copy the newly created FastLogger folder (new logs).
8. Rename the folders (for example: FastLogger_old and FastLogger_new).
9. Compress both folders into a single .zip file.
10. Attach the file to your support case or upload it as instructed.
