Adding License Keys

Two types of license key can be used in conjunction with Enterprise Architect: Private and Shared.

Private Keys

Private keys allow you to register, indefinitely, on the machine and user account that you are currently using:

  • An Enterprise Architect license for the edition of Enterprise Architect you have purchased, or
  • An Add-In product license

Shared Keys

Shared keys are obtained from a central shared key store, to give you temporary access to the installed 'suite' edition of Enterprise Architect. They are available with the purchase of a floating license, and require Enterprise Architect version 4.51 or higher.

Shared Keys require a shared license key store to be configured by your license administrator; the key store can be either file-based or network based (preferred). Only the Key Administrator is required to install the Sparx Enterprise Key Store application; end users simply connect to the configured key file - advised by the administrator - as described here. No additional software is required to be installed.
