Building Excel Real-Time Data Components in Visual Basic .NET

[DAvid]

I followed the instructions in:

http://msdn2.microsoft.com/en-us/library/aa140061(office.10).aspx

It works under XP but fails (badly) under Vista with the error:

Unable to cast COM object of type 'System.__ComObject' to interface type
'Microsoft.Office.Interop.Excel.IRTDUpdateEvent'. This operation failed
because the QueryInterface call on the COM component for the interface with
IID '{A43788C1-D91B-11D3-8F39-00C04F3651B8}' failed due to the following
error: No such interface supported (Exception from HRESULT: 0x80004002
(E_NOINTERFACE)).

I've tried a bunch of workarounds, but with no luck.

Any ideas?
