I just realised that some of the screenshots don't display very well in the notification email. Here's the text from the error message in the RRS Log:
11:50:50.130 (0) Error (0=hex:0). In CScript::Call(SAFEARRAY): Action execution failed: Script Error:
Error: Accusoft.ScanFixXpress8.Net

And here's the text of the error that appears in the base of the Image Enhancement Window:
