When installing older versions of the Copy Audit Touch Administration software, the DLL (Dynamic Link Library) for the Copy Audit Touch Administrator plugin didn't always install the "PrintAudit.CopyAuditTouch.SidePulses.dll" file in the Print Audit 6 Commondirectory.
Solution:
Uninstall and then reinstall the Copy Audit Touch Administrator module using the most recent version. Both the Administrator and Terminal portions of the software should be the same version.
