Error editing Office files on a Windows SharePoint Server

If you get the error "'Edit Document' requires a Windows SharePoint Services-compatible application" then you're missing some Office extension to edit Office files directly from the sharepoint. http://support.microsoft.com/kb/833714

Just go to Add/Remove Software and add the component Windows SharePoint Services Support to Office 2003/2007. Voor Dutch Users: Office Hulpprogramma's >> Ondersteuning voor Windows Sharepoint Services.
