How to: Prepare IIS for Deployment of Office Solutions

  • Article

Users can install Microsoft Office solutions by opening the deployment manifest from the Web. However, a secured installation of Internet Information Services (IIS) will block the .vsto file name extension. The MIME type must be defined in IIS before you deploy Office solutions by using IIS.

Applies to: The information in this topic applies to document-level projects and application-level projects for Microsoft Office 2010 and the 2007 Microsoft Office system. For more information, see Features Available by Office Application and Project Type.
