- Quit Skype.
- Download and extract the logging-related registry files:
- Right-click the zip file and select Extract all, click OK to unzip the file, then navigate to the folder where you extracted the logging-related command files.
- Run logging-on.reg to set the Skype logging-related Registry key.
- Restart Skype.
You can now proceed to replicate your issue. Skype will create log files in its application data folder. The location of this folder differs depending on the version of Windows you're running. Open File Explorer and type %appdata% into the address bar to find it.
Gathering and submitting the log files
Skype for Windows desktop creates two log files: a 'main' log file, which you submit with all issue reports; and a 'trace' log file, which you submit when reporting an issue related to audio/video during a call only:
- 'main' log file: debug-yyyymmdd-hhmmss.log
- 'trace' log file: debug-yyyymmdd-hhmmss.trace.txt
For example, a particular session might produce files named 'debug-20160227-1152.log' and 'debug-20160227-1152.trace.txt'. Log files from the same Skype session will always have the same timestamp, which indicates when the session started.
Submit your logs to us as advised by Skype Customer Service.
Logging with the installer
The Skype for Windows desktop installer also creates an installation-specific log file, which you can attach when reporting installation issues. To run the installer with logging enabled:
- Navigate to the folder containing your installer’s executable.
- Run the installer, specifying the logging option SkypeSetup.exe /log
The installer creates a log file named 'install-<YearMonthDate>.log' in the current folder, with the timestamp indicating when the install started.
