I have a WCF Web service that converts pdf documents, we are currently using apose.pdf 9.2.1 the trail version converts successfully some PDF but some others do not because of the trial limitation giving this error in some cases:
System.ApplicationException: Error calling PDFToTIFF: System.IndexOutOfRangeException: At most 4 elements (for any collection) can be viewed in evaluation mode.
When using the full version of the dll I get the following error in all of the conversions:
I have also tried with the hotfix dll but still no success. What is causing the full the version to fail?
