Unless you are already running Rational DOORS 8.2 or Rational DOORS 8.3, and have a valid maintenance agreement, you must request a new software license for Rational DOORS 9.5. Software licenses for all versions of Rational DOORS 8.1 and earlier are not compatible with Rational DOORS 9.5.
Rainbow dongles are no longer supported by Rational DOORS. If you use Rainbow dongles to run Rational DOORS, you must contact your local Support department. You do not need to replace other existing hardware licenses.
The Rational License Key Server must be installed on your system. For information about the Rational License Key Server, see Rational Common Licensing information.
