Run Time Error - Click to add first slide

I have recently taken over the support of a slide generation web module that works on most systems, but on a particular subset we recieve the attached error.

We have attempted to determine if there are either version or security setting differences, but can not identify anything subtantive. Any ideas?

Dear Tom D,

Thanks for considering Aspose.Slides.

What does the error say? Please post it. The document you attached contains a picture of presentation and I find nothing on it.

The attachment is exactly the system response we get from this subset of users. Unfortunately we don't actually get any error message and the module, using the aspose slide engine, works like a champ on all other systems we've tried it with.

Could there be a security, IE, or MS Office setting related to the behaviour?

Dear Tom D,

I am afraid; I cannot help you in this regard. I am forwarding your question to more knowledgble technical people. I will post here, when I will get any response from to inform you.

Meanwhile, you should test the presentation with error on the systems where others are working fine. If it worked fine there, then we can say, it is because of machine etc

Thanks Shakeel, our thought is it must be a security/permissions issue somewhere. We’ll await your additional feedback.

Dear Tom D,

There could be two possible reasons; either created ppt doesn’t have any slide, we don’t know why either because of security reasons Aspose.Slides doesn’t have write access or all the slides have been accidentally deleted by you.

Normally, if presentation is broken, Power Point gives error e.g “Couldn’t read ppt file” etc.

If problem is still unresolved then please provide us with your presentation and source code for further investigation.

Here is the source code I inherited for this generation process.

The most disorienting element of the behavior is it only occurs on a particular subset of computers that are tightly configuration controlled (e.g. we know they have a common set of software loads).
