Instructions provided describe how to install .NET support for ArcGIS Desktop.
Note: At ArcGIS Desktop 10 users install ArcObjects SDK for .NET (Desktop and Engine included) which also automatically installs .NET support. The setup for ArcObjects SDK for .NET is available on the installation DVD.
Below are the two instances in which .NET support is not automatically installed with ArcGIS Desktop.
• The .NET Framework was not installed on the computer before the ArcGIS Desktop install was performed. • The version of the .NET Framework installed on the computer was not the correct version at the time that the ArcGIS Desktop install was performed.
