Hi
I’m using Aspose.PowerPoint 1.7.9.0 and have problem with a PowerPoint file. The presentation contains only one slide and it seems impossible to set a new presentation object. It working fine with all others presentation I have test with, and I can not see anything strange with this file.
Code:
FileStream fis = new FileStream(source, FileMode.Open, FileAccess.Read);
Presentation pres = new Presentation(fis);
Error message:
“Unable to cast object of type ‘Aspose.PowerPoint.ppt.ac’ to type ‘Aspose.PowerPoint.ppt.m’.”
What is the problem?
