Available with Data Reviewer license.
ArcGIS Data Reviewer Server requires ArcGIS Server. ArcGIS Server must be installed with .NET Extension Support enabled. If you installed ArcGIS Server without .NET Extension support, you must install the correct Microsoft .NET Framework version and then enable it by modifying your ArcGIS Server installation.
For more information about installing ArcGIS Server with .NET Extension Support, see ArcGIS Server system requirements.
Microsoft .NET Framework 3.5 is required to support an Oracle-based scheduler database.
