- Product

Install the Latest Office Updates
Updating Office is the most effective solution, as Microsoft frequently patches known crash issues related to the Compare feature in newer software builds.
Many users have reported that the Compare tool crash is a known bug in specific Office versions. Updating to the latest build (such as Version 2208, Build 16.0.15601.20526 or newer) generally resolves the instability.
Open PowerPoint and create a blank presentation. Click on 'File' in the top-left corner, and then select 'Account' from the bottom-left menu.
Click the 'Update Options' button next to Office Updates, and choose 'Update Now' from the drop-down menu.
Wait for Office to download and install the latest updates, then restart PowerPoint and attempt the Compare action again.

Start PowerPoint in Safe Mode
Launching PowerPoint in Safe Mode allows you to determine if a third-party add-in or extension is causing the application to crash during comparisons.
Perform an Online Repair of Office
If updates and Safe Mode do not work, repairing the Office installation can fix corrupted system files like POWERPNT.EXE that trigger sudden application closures.

Frequently Asked Questions
Why does the Compare feature cause PowerPoint to crash?
This is often caused by a known software bug in specific Office builds, conflicts with third-party COM add-ins, or corrupted background components like POWERPNT.EXE failing when processing complex presentation differences.
Will I lose my edits if PowerPoint crashes during Compare?
If AutoRecover is enabled, you may be prompted to restore the file upon reopening PowerPoint. However, unsaved changes made right before the crash occurred might be lost, so it is best to save manually before initiating a comparison.
What version of Office fixes this Compare crash?
Microsoft has resolved this issue in newer software updates. Users have reported that updating Office to Version 2208 (Build 16.0.15601.20526) or a more recent release successfully fixes the crash.
Is there a temporary workaround for the PowerPoint crash?
As a temporary measure, you can split your presentation into smaller files or make a minor, harmless edit to the file before comparing. However, updating your Microsoft Office suite remains the preferred and most reliable resolution.
