Handling previous versions
If you have an older version of ArcGIS installed on your computer, you will need to remove this and any associated ArcGIS software. Uninstall ArcGIS 9.0 Desktop, ArcGIS ArcInfo Workstation 9.0, and the ESRI Software Documentation Library, if they are listed. If you have any additional extensions for ArcGIS, uninstall these as well. You do not have to uninstall the ArcGIS 9.0 License Manager.
If you were using ArcGIS 9.0 with a license manager, you do not need a new hardware key or new keycodes to use version 9.1. Only 9.1 Network Analyst and Schematics extensions require new keycodes. If you are upgrading from ArcGIS 8.3, you will need new keycodes.
Note
You do not have to uninstall ArcView 3.x to install and run ArcGIS Desktop 9.1. ArcGIS 9.1 Desktop defaults to a different folder and will not conflict with ArcView 3.x.
