Interop Assemblies for Office 2003 were installed. When the program
code does the tries to run Microsoft Word 2003 exception with message
"Unable to cast COM object of type
'Microsoft.Office.Interop.Word.ApplicationClass' to interface type
'Microsoft.Office.Interop.Word._Application'. This operation failed because
the QueryInterface call on the COM component for the interface with IID
'{00020970-0000-0000-C000-000000000046}' failed due to the following error:

throw new Exception(ex.Message, ex);

}

object templName;

I believe under this scenario the reference to the Office 2007 PIAs is still
listed in the Registry, so your application will be redirected to the
incorrect set of PIAs. Thus the error.

Hi Sindy,
Thanks a lot for your answer.
I have red the topic you speciefed on the Microsoft Forum. I have looked the
registry key speciefed in this post - it exists and the reference onto the
msword.olb is correct but it's unable to run MS Word yet.
What should I do more again to find the solution of this problem?

Thanks in advance.
