This happens when Office 2003 installed along with SharePoint Designer – a 2007 product.
This problem occurs if the following conditions are true, in the order in which they are presented:
– You install a Microsoft Office 2003 product on the computer.
– You install one or more 2007 Office system programs on the computer.
– You repair or update the installation of an Office 2003 product.
In this scenario, the older version of the Name.dll file becomes the registered version. When the Owssupp.dll file is used, it tries to use functionality that is not available. This condition causes Internet Explorer to crash (stop responding).
