Visio export error "object reference not set to an instance of an object" (64-bit


I am unable to export any Bizagi file into Visio. Trying this results in the error "object reference not set to an instance of an object".

I am using the 64-bit version of Bizagi version and I'm uploading the file in question.

Also, can anyone confirm that this object reference is not in any sense an editable object in a Bizagi diagram but more to do with the C++ code?

Many thanks in advance. Hope to contribute to this community myself in the future.

please answer the basic question. I doubt that it is a bug.

The failure still occurs and I think there is a mistake made by the operator (me) behind it. Last time I solved it but unfortunately I did not document how.

So please explain what this message means.

Thanks a lot.
