If you’re using a pre-built LibreOffice on Linux, list the exact versions of LibreOffice packages in your package management system. If you’re using Windows, list the exact filename of the installer, and from where it was downloaded.
- Including information about installed and used localization (UI language, document language) might be useful.
- Include whether a 32-bit LibreOffice is used on a 64-bit (Linux) system.
- Include the package source if it’s not the official LibreOffice build.
