Question:
I need to support either 32 or 64 bit Outlook, but after adding PDFNet and PDFNetLoader to my addin project, it never loads PDFNet at all.
Answer:
By default PDFNetLoader is looking for a folder called “PDFNet” in the current working directory, but this folder is probably in a different folder.
In particular for Office AddIns, try setting the PDFNetLoader Path to AppDomain.CurrentDomain.SetupInformation.ApplicationBase.
private static pdftron.PDFNetLoader loader = pdftron.PDFNetLoader.Instance().Path(AppDomain.CurrentDomain.SetupInformation.ApplicationBase);
