How to make the Powerpoint file as Non-editable(read only)

I found an old thread on this topic dated 2008-2009.

I was wondering if any progress has been made to address this issue - how to produce pptx file using PresentationEx that will be read only.
Thank you,

Hi Natasha,


I like to share that the support for protecting the presentation and setting in read only mode has been included in Aspose.Slides for .NET. Please visit this documentation link for your convenience and share with us if there is any issue on your end.

Many Thanks,
