In ArcGIS, how do I change the product level?

To change the ArcGIS product level:

1. Log into the computer with an account that has administrator privileges.
   
   
2. Close all open ArcGIS desktop applications (ArcMap or ArcCatalog).
   
   
3. From the Start menu, select Programs or All Programs, then ArcGIS, and then ArcGIS Administrator.
   
   
4. In the left side of the dialog box, click the Desktop folder.
   
   
5. In the right side of the dialog box, select the desired product level, and then click OK.

   Note: Select ArcInfo (Concurrent Use) only if you have purchased an ArcGIS ArcInfo license through UITS. If you have purchased an ArcGIS ArcView license, select ArcView (Concurrent Use). UITS does not sell ArcView Single Use licenses.
