PowerPoint Can't Open This File
Check whether the presentation has a wrong real format, malformed PPTX XML, broken relationships, missing internal files, or another detectable file-side blocker.
ARADURU checks file-side evidence in your browser first, then separates file problems from app or website problems.

PowerPoint can refuse a file for more than one reason
The file itself is the first place to check. If its current PPTX structure looks healthy, the next cause may be access, security, application behavior, or unsupported content.
The file is not really a PPTX
A filename can end in .pptx even when its contents are actually PDF, ZIP, another Office format, or something else.
A required internal target is missing
The presentation can reference a slide, layout, note, or other internal part that cannot be resolved.
The basic structure may be healthy
If no obvious file-side blocker is found, continue outside the file instead of forcing a repair.
How ARADURU checks this PowerPoint problem
Detect the real file format before trusting the .pptx filename.
Validate the PPTX package, presentation XML, slides, and relationships.
Check supported layouts, notes, and chart parts when they are referenced.
Separate a concrete blocker from a healthy basic file structure.
How to interpret the match level
ARADURU found concrete PPTX evidence that can directly or strongly contribute to this PowerPoint problem.
A file-side warning may be related, but it does not prove the complete PowerPoint cause by itself.
The current PPTX checks did not explain the problem. Continue troubleshooting outside the basic file structure.
What this check cannot prove
ARADURU cannot observe PowerPoint runtime errors, Protected View, permissions, endpoint security, file blocking, every embedded object, or every presentation feature.
Common questions about this PowerPoint problem
Can a file simply be renamed to .pptx?
No. Renaming does not convert its contents. ARADURU compares the filename with the detected internal format.
What if a real PPTX contains a structural issue?
That can contribute to an opening failure, but preserve the original and work on a copy or obtain a fresh source file first.
What if the PPTX looks healthy?
Continue with PowerPoint, permissions, security, file blocking, or unsupported-feature troubleshooting.
