What you’ll need

• A computer running Windows ⁄₁₁, macOS 10.14+ (or later), or a modern Linux distribution.

Downloading Kernel for Impress

1. Visit the official Kernel for Impress download page or the LibreOffice extensions site.
2. Choose the installer that matches your operating system (Windows .msi/.exe, macOS .dmg, or Linux .deb/.rpm/LibreOffice extension .oxt).
3. Save the file to an easy-to-find folder (Downloads).

Installing on Windows

1. Double-click the downloaded installer (.msi or .exe).
2. If prompted by User Account Control, click Yes to allow changes.
3. Follow the installer steps — accept the license, choose installation directory (default is fine), and click Install.
4. Once installation completes, restart LibreOffice Impress if it was open.

Quick tip: If Kernel for Impress is packaged as an .oxt, open LibreOffice, go to Tools → Extension Manager → Add, then select the .oxt file and install.

Installing on macOS

1. Open the downloaded .dmg file and drag the Kernel for Impress app or installer into Applications (or run the packaged installer).
2. If macOS blocks the app from running, open System Preferences → Security & Privacy and allow the app under the General tab.
3. If the extension is an .oxt, open LibreOffice, then Tools → Extension Manager → Add, select the .oxt and install.
4. Restart LibreOffice Impress.

Note: For Apple Silicon (M1/M2), use the universal or arm64 build if available.

Installing on Linux

• For .deb/.rpm packages:
  • Debian/Ubuntu: sudo dpkg -i kernel-for-impress_.deb && sudo apt-get -f install
  • Fedora/openSUSE: sudo rpm -i kernel-for-impress-.rpm or use your distro’s package manager.
• For .oxt:
  • Open LibreOffice → Tools → Extension Manager → Add → select the .oxt file.
• After installation, restart LibreOffice Impress.

Post-installation: Initial configuration

1. Open LibreOffice Impress.
2. Go to Tools → Add-Ons or Tools → Extensions (may differ by version) to verify Kernel for Impress is enabled. You should see the Kernel for Impress entry and version. Ensure it’s enabled.
3. Open Tools → Options → Kernel for Impress (or Kernel settings) to access the extension’s configuration panel.

Key settings to configure quickly:

• Default template integration — enable if you want Kernel features applied to new presentations automatically.
• File compatibility mode — choose strict or permissive depending on whether you collaborate with Microsoft PowerPoint users. Choose “compatibility” mode for best cross-platform fidelity.
• Performance tweaks — enable hardware acceleration if available; set cache sizes moderately for smoother playback.
• Autosave and recovery — set autosave interval to 5–10 minutes.

Common additional setup tasks

• Keyboard shortcuts: Tools → Customize → Keyboard — assign or change shortcuts provided by Kernel for Impress.
• Add-ons and templates: Tools → Templates → Organize to import any Kernel-provided templates or themes.
• Media codecs: If video/audio fails to play, install the platform-specific codecs (e.g., K-Lite on Windows, ffmpeg on Linux/macOS via Homebrew).

Quick troubleshooting

• Extension not visible: Close LibreOffice fully (check Task Manager), then reopen. If still missing, reinstall the .oxt via Extension Manager.
• Crashes on start: Start LibreOffice in safe mode (Help → Restart in Safe Mode) and disable Kernel for Impress; try reinstalling.
• Videos/audio not playing: Install ffmpeg and ensure file formats are supported; convert to MP4 (H.264/AAC) if necessary.
• Permission errors on Linux: ensure installed files are owned by root and have correct permissions; run installer with sudo.

Best practices for fast setup

• Use the latest LibreOffice version supported by Kernel for Impress.
• Keep autosave enabled and backups active while you configure features.
• Apply settings to templates so new presentations inherit them automatically.
• Test on a small sample presentation before migrating large projects.

Example: Rapid setup checklist (5–10 minutes)

1. Download the correct installer for your OS.
2. Install the package or add the .oxt via Extension Manager.
3. Restart LibreOffice Impress.
4. Open Kernel settings → set compatibility mode and enable templates.
5. Set autosave to 5 minutes and enable hardware acceleration.
6. Import one template and test media playback.
