What’s wrong,how to fix it?

@ducaisoft,
Thank you for contacting support.

Please test the problem you decribed with the latest version of Aspose.Slides if it is possible. If the issue persists, please share the following data:

  • input and output files
  • OS version on which the problem occurred

I Tested the dll v22.2 on VS2017, Win10 Home Edition,VB.net 4.6.1, the issue still on for any ppt file.

Another error is that the PPT.Save(OutFile, Global.Aspose.Slides.Export.SaveFormat.Pptx) method will be hanged, what’s wrong. Whereas PPT.Save(OutFile, Global.Aspose.Slides.Export.SaveFormat.Ppt) method is ok but the file size of outfile is still 0. What’s wrong?
