Error "The server application, source file, or item cannot be found" when trying to open an embedded PDF from Power PDF in a Word Document on a computer that does not have Power PDF installed
This is a known issue with OLE embedded objects with MS Office. When you embed an object into an Office Document, Microsoft embeds the program information for the source program. So, if you embed a file from Power PDF, you must have Power PDF to open the file. You will have the same issue with any PDF program that is not Adobe if the recipient only has Adobe Reader. You would see the same error message if you double-click a bitmap image object in a Word document on a workstation that does not have MS Paint.
You can google that error message and see more information on this from Microsoft. Unfortunately, there is nothing we can do about that on our end, other than recommend avoiding embedded objects. The client should consider using a PDF portfolio that contains the Word document and the PDF.
