unable to cast error

C

Please help I can not get past this issue.



I recieve this error on the example "How to use automation to get and to set
office document properties." http://support.microsoft.com/kb/303296/en-us
this was the recommended fix for this issue.



I can run this same example on my xp machine with office 2003. When I try
this example on my vista machine with office 2003 I get the following error.

System.InvalidCastException was unhandled
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:
No such interface supported (Exception from HRESULT: 0x80004002
