Some more info that I don't know what to do with -- but maybe others know: Using Microsoft's OLE/COM Object Viewer I find 'MGCPCB.ExpeditionPCBApplication' under Automation Objects but 'MGCPCBAutomationLicensing' under Type Libraries. In coclass 'Application', a method 'GetToken' is listed, so everything looks fine here.

It even looks like the access to the 'MGCPCBAutomationLicensing' Type Library works up to a point: when I change the class name to something other than 'Application' the error message changes from '...module could not be found' to 'error 0x800401f3: "Invalid class string"'
