PDF comparison issue in CompareWith method.Comparison using .NET

GroupDocs.Comparison Product Family
1

I face a problem when testing the compare functions on pdf documents that we produce with our software. The pdfs have about 17 pages.

The error appears immediately after calling the Compare() Function on the documents The error is: ‘Error convert to model in CompareWith method.Comparison cannot convert document to normal model.’

I’m not allowed to upload the doucments to the public here.

Any help? We doing tests on our evaluation licence and want to decide whether to buy a full licence or not. Hope to get an answer soon.

Best, Harald
