We have been successfully using PDF-XChange 4 SDK PRO since 2011. We are now in the course of updating to version 6. Two days ago I have downloaded PDF-XChange 6 SDK PRO Setup (Version 6.0.317.1) for that purpose and am gradually extending our software to support version 6 (alongside 4). While testing I encountered the following problem with the driver API: none of the synchronous nor asynchronous events (PXCComLib6.CPXCPrinter.OnStartDoc, OnFileSaved, OnDocEnd etc.) are being fired, even though pdf files are being created. I have also tried the example provided within the SDK's installation directory (PDFdriverAPI), with the same result (in both, DEBUG and RELEASE).
Development environment: Window 10 Pro 64-Bit Version 1511 (OS Build 10586.545), Visual Studio Professional 2015, C# .Net 4.0, and have installed versions 4 and 6 of PDF-XChange SDK PRO.
Note: version 4 works without any issues, thus throwing all events as expected.
Is there anything I'm missing?
Any help greatly appreciated!
