Hey Jean-Marc,
This error typically indicates that a library referenced in the program isn't found.
Since you've already checked the Windows registry without success, it might be worth examining the configuration settings within ACS itself. Ensure that the library references are correctly configured in ACS for all your servers. Sometimes, discrepancies in library configurations between different servers can lead to such errors.
Additionally, verify the library list settings in your ACS sessions. It's possible that the library you're trying to access isn't in the library list ACS is using. Adjusting the library list to include the necessary libraries might resolve the issue.
Since you mentioned that ACS works fine on printers' output when you're at a client site with one server, it could suggest that there might be a difference in the environment setup between your local environment and the client's environment. Comparing the ACS configurations between the two setups might provide some insights.
If these steps don't resolve the issue, it might be beneficial to consult with your IT support team or the ACS documentation for further troubleshooting steps specific to your setup.
Hope this helps you get closer to resolving the problem and extracting those PDF files from the spool. Let me know if you need further assistance!
