setting Shape.WrapFormat.Type failing with RPC_E_SERVER_FAULT

[Ram Kumar Karnataka]

Hello All,
I'm using Word automation using VS2005 and C#.
I'm facing a strange problem while setting Shape.WrapFormat.Type to
Word.WdWrapType.wdWrapSquare.

In all the machines where our application runs(German & English MS-Word),
the following line is getting executed fine except in one machine where it
failed with RPC_E_SERVER_FAULT exception.
shape.WrapFormat.Type = Word.WdWrapType.wdWrapSquare;
That machine has Word2003 with SP3. Even its failing in that machine when
we try to get the WrapFormat.Type property.

Please find below the exception call stack

//While getting the property WrapFormat.Type

23.07.2008 08:08:49 Exception
Type=System.Runtime.InteropServices.COMException
Message=Beim Aufruf einer COM-Komponente wurde ein HRESULT E_FAIL-Fehler

Can you please throw some light why this can happen. Can you please reply me
back asap. And this PC has German Word and German XP.


Thanks
Best Regards
