Hi,
I get no AttributeError with IronPython 2.0 Alpha 7.
thanks
> 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.

>> The behavior currently depends on whether or not the RCW gets strongly-typed when it enters the managed world. As a workaround, the following registry script Misha provided could "fix" your machine by registering the PIA:
>>
>> Windows Registry Editor Version 5.00
>>
>> [HKEY_CLASSES_ROOT\CLSID\{00024500-0000-0000-C000-000000000046}\InprocServer32]
>> "Assembly"="Microsoft.Office.Interop.Excel, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71E9BCE111E9429C"
>> "Class"="Microsoft.Office.Interop.Excel.ApplicationClass"
>> "RuntimeVersion"="v1.1.4322"
>>
>> [HKEY_CLASSES_ROOT\CLSID\{00024500-0000-0000-C000-000000000046}\InprocServer32\12.0.0.0]
>> "Assembly"="Microsoft.Office.Interop.Excel, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71E9BCE111E9429C"
>> "Class"="Microsoft.Office.Interop.Excel.ApplicationClass"
>> "RuntimeVersion"="v1.1.4322"
>>
>> Your script should work independent of whether the PIA is registered or not. We will look into it and see what is going.

>> The implementation of -X:PreferComDispatch is still not complete. We are working on improving it and will enable it by default once all issues are flushed out. You are on the cutting edge and providing us with advance feedback :)
