I have an app comprising one ActiveX DLL (compile option set to project compatibility) and one standard exe that loads the DLL. When I run these in the development environment, they run successfully. When I compile the project group that contains both projects, quit the IDE without taking any further action (so it hasn't affected the COM registration of the DLL), then run the exe, it gives an automation error. Loading up and running from the IDE again behaves fine.
Does anyone have any pointers to first steps I can take to debug this issue? Finding out what's being attempted would be a good start - this uses CDO and a bunch of other libraries, so it may not be my DLL that's failing.
