Misha said - "I should add that having the registry keys alone would only help
if Excel PIAs are in the GAC as well (when installing Excel - you would choose
.NET Interoperability support)." You probably do not have the PIAs installed.
The problem is just a matter of initialiazation order. The IDispatch support
was not initialized by the time the "e.Visible = True" statement was executed.
I have a fix and have just checked it in. The next IronPython drop should have
the fix. If you want a fix now, you can add the following lines at the very
start of PythonBinder.GetExtensionTypes.
// Ensure that the type is initialized. If
ReflectedTypeBuilder.RegisterAlternateBuilder was used,
// the alternate builder will get a chance to initialize the type.
DynamicHelpers.GetPythonTypeFromType(t);
