Troubleshooting ImpressRunner—the classic OpenOffice and LibreOffice extension used to automatically start presentations in full-screen mode or autostart .pps files—usually comes down to correcting metadata mismatches, file paths, or suite compatibility issues.
Here is how to resolve the most common ImpressRunner errors quickly.
1. Presentation Fails to Autostart (File Opens in Edit Mode)
This occurs when the extension is active but cannot detect the correct flag inside your native OpenDocument Presentation (.odp) file.
The Fix: Open your presentation and navigate to File > Properties > Custom Properties. Add a new property string. Set the property name or userfield value exactly to autostart (all lowercase, no quotation marks). Save and close the document.
2. PowerPoint .pps / .ppsx Files Do Not Launch Automatically
ImpressRunner is specifically designed to bridge the gap for PowerPoint slideshow files that should launch instantly. If they open to the editor layout instead, system file associations are misconfigured.
The Fix: Right-click the .pps or .ppsx file in your operating system’s file manager. Select Open With, choose your main OpenOffice/LibreOffice application suite, and check the box to “Always use this app to open this file type.”
3. Extension Corrupted or Non-Responsive After an Office Update
Major software upgrades to LibreOffice or OpenOffice frequently break older extensions like ImpressRunner due to changes in the underlying API.
The Fix: Open your office program and go to Tools > Extension Manager. Find ImpressRunner in the list, click Remove, and restart the software. Download the latest .oxt package file from the extension repository and reinstall it fresh. 4. Missing ImpressRunner Action Buttons
If the extension is active but you cannot find the toolbar buttons used to toggle the autostart property on your presentations:
The Fix: Go to View > Toolbars from the top menu bar. Look for the ImpressRunner entry in the list and ensure it is checked. If it is checked but still invisible, choose Customize under the toolbars menu to manually drag the toggle buttons back onto your active workspace. 5. Infinite Loading or Application Crash on Launch
If your entire office suite freezes or crashes the exact moment an autostart presentation is triggered, your user profile cache has likely bottlenecked.
The Fix: Launch LibreOffice or OpenOffice in Safe Mode (usually found via the Help menu or via command line). If it launches fine, reset your user profile. For a manual reset on Linux, back up and clear the ~/.config/libreoffice folder; on Windows, clear the equivalent directory inside your %APPDATA% folder. To help isolate the exact problem, let me know:
Which office suite and version are you running (e.g., LibreOffice 24.2, older OpenOffice)?
What is the file format of the presentation you are testing (.odp, .pps, .pptx)?
Are you seeing a specific error message or popup when it fails? Starting an ODP presentation automatically
