Some notes about installing ArcGIS 10.7:
The ArcGIS 10.7 setup packages are designed to detect and upgrade an existing installation of the same ArcGIS product. The settings for the installation location and authorization information are retained during the upgrade. See the installation guide for more information on installation upgrades and new installations.
ArcGIS 10.7 Single Use Licenses:
If ArcGIS 10.7 will be installed on a machine that is different from where a previous ArcGIS 10.x product is currently installed and you wish to use the existing ArcGIS 10.1—10.6.1 authorization number for ArcGIS 10.7, the earlier version of an ArcGIS 10.x product must first be deauthorized before authorizing ArcGIS 10.7.
ArcGIS 10.7 Concurrent Use Licenses:
- The copy protection mechanism for ArcGIS Desktop 10.7 and ArcGIS Engine 10.7 Concurrent Use requires that ArcGIS License Manager 2018.1 be installed to support these products.
- Existing ArcGIS 10.1—10.6.1 authorization numbers will work with ArcGIS Desktop and Engine 10.7.
- Existing ArcGIS Enterprise 10.6—10.6.1 authorization numbers will not work with ArcGIS Enterprise 10.7. You must obtain a 10.7 authorization number.
