Something seems to be amiss with Adobe Reader X and Dynamics GP. Yesterday we upgraded Adobe Reader to version X on our Terminal Server, where our Dynamics GP application resides.
Till then, users were able to attach PDF files to GP records using OLE Object Container. But post upgrade, all users are facing the following error message whenever they try to attach a PDF file or view an existing PDF attachment:
Looks like I am not the only one to face this issue. There is a community forum post which raises the same question. Link to that post: Errors when opening or creating PDF OLE Attachments in Dynamics GP notes.
Not sure how to resolve this at the moment, other than retaining older version of Adobe Reader.
