PowerPoint Slide Is Generating an Error after Downloading a Presentation and When We Try to Open the File

Aspose.Slides Product Family
1

We use Aspose version 19.7.0.0. For some reason when we try to download a PPT after it’s been processed by ASPOSE, we get an error
“Sorry, PowerPoint can’t read c:\Users.…filename.ppxs”
The file only has one slide. Can’t figure out what’s in this slide that’s causing the error.

It seems you are encountering an error when trying to open a PowerPoint file generated using Aspose.Slides version 19.7.0.0. The error message indicates that PowerPoint found a problem with the content in the file, which suggests that there may be an issue with how the slide was created or saved.

Here are some steps you can take to troubleshoot and potentially resolve the issue:

  1. Upgrade Aspose.Slides: Consider upgrading to a newer version of Aspose.Slides. Users have reported similar issues with version 19.7.0.0, and upgrading to version 20.2 or later may resolve the problem. Newer versions often include bug fixes and improvements that could address the issue you are facing.

  2. Check the Source Presentation: If possible, review the source presentation that you are using to generate the new PPTX file. There may be elements in the original presentation that are causing issues during the conversion process.

  3. Test with a Simple Slide: Create a new PowerPoint presentation with a simple slide (e.g., just a title) and see if you can generate a PPTX file without errors. This can help determine if the issue is specific to the content of the original slide.

  4. Review the Saving Process: Ensure that the code used to save the presentation is correct. For example, make sure you are using the appropriate save format and that the file path is valid.

  5. Provide Sample Files: If the issue persists, consider sharing the source presentation and the generated PPTX file with Aspose support for further investigation. This can help them identify the specific cause of the error.

If you follow these steps and still encounter issues, it may be beneficial to reach out to Aspose support with detailed information about your implementation and the files involved.
