Reading time: 2 min.

When a technical issue arises in Archicad, it is often necessary to have detailed information about what is happening in the background. For this purpose, Graphisoft has developed FastLogger, a tool that records system and Archicad activity at the moment the error occurs.

These logs allow the technical support team to precisely analyse the source of the fault and offer a faster, more effective solution. Below is an explanation of how to generate and send these files.

What Is FastLogger?

FastLogger is a utility built into Archicad (Windows and macOS) that collects advanced diagnostic information.

The resulting file includes system data, Archicad processes and relevant events. It does not contain sensitive user or project data, only the technical information needed for analysis.

How to Obtain FastLogger

1. On Windows
   1. Reproduce the error.
   2. Close Archicad.
   3. Go to the following location on your PC:
      C:\Users\<username>\Graphisoft\Archicad Log Folder\<Archicad version>\FastLogger
   4. Copy or upload the most recently created file to the required location.
      
2. On macOS
   1. Reproduce the error.
   2. Close Archicad.
   3. Open Finder and go to:
      System drive/Users/<username>/Library/Logs/Graphisoft/Archicad Log Folder/<Archicad version>/FastLogger

   4. Copy or upload the most recently created file to the required location.

Conclusion
FastLogger files are essential for speeding up the diagnosis of issues in Archicad. By following these steps, you will be able to provide support engineers with the information they need to find the cause of the error and resolve it more quickly.
