There is a dialog style that allows the dialog to be created even if there are errors. The
most common error is a missing DLL or improperly registered ActiveX control. If you tweak
the dialog style bit that allows it to come up even with errors, the missing control will
tell you where the problem is.

Note: I believe you can actually set this bit in the executable by opening the executable
image (.ocx file, presumably) in visual studio in Resource mode and editing the dialog
resource.
