You cannot create a new document or check out an existing document in a Windows SharePoint Services 3.0 document library when you have multiple versions of Office installed

You connect to a document library in a Microsoft Office SharePoint Server 2007 site or in a Microsoft Windows SharePoint Services 3.0 site by using Windows Internet Explorer 7 or Microsoft Internet Explorer 6. However, when you try to open a Microsoft Office document, Internet Explorer crashes (stops responding). Additionally, when you click New Document, the button does not work. You cannot create a new document. 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.

Note The workaround in this article resolves this issue only if you are using a combination of Office 2003 and the 2007 Microsoft Office system, as the previous bullet points describe. Although you may experience this problem with other Office versions, the workaround in this article will not resolve the issue for other versions. You may not see "Microsoft Office 2007" when you look in Add/Remove Programs. Instead, you may see a stand-alone product such as Microsoft Project 2007, OneNote 2007, or Expression. See the "More Information" section for references to articles that discuss other Office version combinations.

This problem occurs because 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).

If you use a version of Microsoft Office other than Office 2003 and the 2007 Office system, click the following article numbers to view the article in the Microsoft Knowledge Base: The controls that enable features, such as the Edit Document feature on a Windows SharePoint Services document library, are shipped together with the 2007 Office system and Office 2003. These controls must be installed to access most of the integration features in Office.

These controls are listed as Windows SharePoint Services Support under Office Tools when you use one of the following methods:

• You perform a custom installation of a 2007 Office system or of an Office 2003 system.
