This seems to be a known problem without a known solution.
We have a SQL database backend and an Access 2003 frontend. The Access client displays scanned PDF documents via an embedded OLE Object field.
Up until recently, we had been using Acrobat Reader 6.0 as the default viewer, but we switched up to 9.2 so that our staff could read external PDFs with security/encryption,etc. When an embedded PDF is viewed now through the Access client, an error is thrown when Acrobat Reader is closed, indicating that an OLE server was not registered, or needed to be re-installed. This did not happen with the Acrobat 6.0 client.
Is there any automatic behind-the-scenes file updates being performed when Acrobat Reader 9.2 shuts down? It seems like some information is trying to be written (maybe a timestamp?) and is kicking back an error when it can't update the target file.
Is there a workaround for this? I need the ability to read secured PDFs, but I also don't want my users having to needlessly deal with persistent error messages.
