Hi Shai,
I have observed your comments and like to share with you that I am able to reproduce the problem with the LinkFileName property and a ticket with ID SLIDESNET-37086 has been logged into our issue management system for further investigation and resolution of the issue. This thread has been linked with the issue so that you may be notified automatically as soon as the issue will be resolved.
About the problem while saving the file, I am not able to observe any issue while saving the presentation as a pptx file by using the code below. I have also attached the generated output file for your kind reference (see OLEsaved_By_Aspose.pptx). A presentation can not be saved as an exe file so please elaborate what exactly do you mean by saving as exe, so that we may proceed further to help you out.
Presentation pres = new
Presentation(@“D:\Presentation.pptx”);<o:p></o:p>
pres.Save(@"D:\OLEsaved_By_Aspose.pptx",
SaveFormat.Pptx);
We are sorry for your inconvenience,
