Exception"The given key was not present in the dictionary." while loading presentation(.NET)

Hey Team,

I’m using Aspose Slides .NET 17.12 in a business application but I’m receiving an error when trying to open certain powerpoint files.

Error is : “The given key was not present in the dictionary.”

An example of one of the affected files is attached. It only gives the error on certain presentations.

Code is simply this line to reproduce:

Presentation presentation = new Presentation(“C:\ProblemPresentation.pptx”);

ProblemPresentation.pptx is attached to help reproduce the error.

The same error occurs when opening as a memory stream as well.

Thanks in advance for any help you can provide,

Hi. Could you give us an approx date this issue will be resolved by? If it’s going to be more than a couple of weeks from now, we will need to look into a workaround or replace the library entirely.

Thanks,
