Uninstalling ArcGIS products

If the following products are installed on your machine and are a version previous to ArcGIS 10.1, they must be uninstalled before proceeding with the ArcGIS 10.1 for Desktop setup. All ArcGIS products previous to version 10.1 must be uninstalled before installing any ArcGIS 10.1 product.

IMPORTANT

Esri strongly recommends that all sample and third-party extensions or plug-ins be uninstalled before installing a newer version of ArcGIS. Remove these from your computer before uninstalling ArcGIS products. Contact the distributor or manufacturer to confirm that they are supported with the ArcGIS version you are installing. If they are, you can install them again after completing the ArcGIS installation.

• ArcGIS Desktop
• ArcGIS Desktop Developer Kit
• ArcInfo Workstation
• ArcReader stand-alone
• ArcGIS Engine Runtime
• ArcGIS Engine Developer Kit
• ArcGIS Server
• ArcGIS Server .NET ADF
• ArcGIS Server Java ADF
• ArcIMS
• Python and NumPy (not required, but it is highly recommended that you remove these)

The ArcGIS for Desktop setup will terminate and display a dialog box if conflicting versions of these products exist on your machine. If so, you must uninstall each of them then run the ArcGIS for Desktop setup again to proceed with your installation.

As long as the installed products are all version ArcGIS 10.1, they can coexist on your computer without conflict.

Note:

Use Add/Remove from the Windows Control Panel to manually uninstall these products. An uninstallation utility, available on the media, can be run to remove previous ArcGIS products.

This utility displays a list of existing 9.x ArcGIS software that must be uninstalled prior to installing ArcGIS 10.1. This utility does not detect any third-party applications or extensions; those must be manually removed.
