Setting the program access and defaults to Microsoft Windows allows ArcGIS to properly open geoprocessing tools.

  1. Close any running ArcGIS applications.
  2. For Windows XP: From the Start menu, open 'Set Program Access and Defaults'.

    For Windows Vista / Windows 7: From the Start menu, open 'Default Programs' and click 'Set Program Access and Computer Defaults' in the next window.
