I am trying to download Office 2007 files (docx) on XP SP2-3 workstations (with office 2007 installed) from IIS6 server (w2003). When I choose to save the file (at IExplore prompt) Save as dialog recognizes docx file as compressed folder. I checked MIME extensions on IIS – all office 2007 extensions are added. So is there any way to change this? I want XP to recognize offic documents as office documents.
