PowerPoint found a problem with content, what to do
This prompt means PowerPoint read the presentation, found content it cannot load somewhere in the deck, and is offering to repair the file by removing or fixing the damaged part. In the large majority of cases the repair works and loses little: one slide's media, an embedded chart, or a font object. Files downloaded from the internet can also trigger a close cousin of this prompt until they are unblocked.
The fix, in order
- Copy the file, then accept the repair on the copy. Click Repair when prompted. PowerPoint reports which slides it could not read. Save the result under a new name and check the slides it flagged before trusting the deck.
- Unblock a downloaded file. Right-click the file, Properties, and if an Unblock checkbox appears at the bottom of the General tab, tick it and retry. Windows marks files from the internet, and that mark alone can trigger content warnings.
- Open it from a trusted location or move it local. Copy the deck out of a sync folder or network share onto the local drive and open it there. A half-synced file reads exactly like a corrupt one, and the sync copy often completes a minute later.
- Isolate the damaged slide by halves. Create a blank deck, then use Home, Slides group, Reuse Slides to import slides from the broken file in halves. The half that fails contains the bad slide; narrow down until one slide is identified, then rebuild that slide manually in the new deck.
- Check embedded media and fonts on the bad slide. A corrupted video, an unusual embedded font, or an object pasted from another program is the usual culprit. Reinsert the media from its original source file rather than copying it from the old slide.
- Recover an earlier version. File, Info, Manage Presentation lists AutoRecover copies, and the file's Properties, Previous Versions tab may hold a shadow copy. A deck from an hour ago with one slide to redo beats a heroic repair.
If it still happens
If every presentation from one sender triggers this prompt, their template or a shared slide library element is damaged, and every deck built from it inherits the fault. Rebuilding from a clean template ends the pattern, while repairing each deck individually does not.
Common questions
Is it safe to click Repair? Yes, on a copy. Repair modifies the file by removing content PowerPoint cannot read, so working on a copy keeps the original intact in case a different route recovers more.
Why does PowerPoint open the file fine on another computer? The damaged part may be a font or codec that the other machine has and this one lacks, or the copy on the other machine is a different, intact version from the same source. Compare file sizes to check whether they are the same file at all.
