...
Looking for file C:\Program Files (x86)\SAP\ACSWrapper.dll
Error loading ACSWrapper.dll
...
Environment
- S/4HANA Public Cloud, all versions
- Cloud Print Manager (CPM), as of version 760
Cause
The ACSWrapper.dll is only important for SAP GUI and SAPSprint.
ACSWrapper is the interface between the C++ coding for SAP GUI and SAPSprint and the C# coding for Aspose PDFPRINT.
However, for CPM the interface is not necessary since it is completely written in C#. The message is still written because it is located in a common module.
Resolution
The message can be ignored in CPM case. Correct document processing is still expected even with this message.
In SAP GUI and SAPSprint scenario, the message "Error loading ACSWrapper.dll" means that the SAPPDFPRINT could not be loaded correctly.
