How to get your earlier version licenses and downloads

Named user licenses, 5-packs or 10-packs

• Each serial number that also requires an older version license must be registered to a unique Embarcadero Developer Network (EDN) account that is associated with the intended end user of the product.
• You must install and register your 10.x serial number before you request the older version licenses.
• You must request your older version licenses within 180 days of your purchase of the 10.x product.
• Your earlier version licenses will be tied to your user account and cannot be given away or sold. If your 10.x license is an upgrade, you will not receive additional licenses for older versions that you already own.
• Older versions are available for the core product and for the Professional Mobile and FireDAC Client/Server Add-On Packs

Named or Concurrent licenses

• If you purchased Network Named or Concurrent licenses, the older version licenses for versions 2007-10.2 Tokyo will be included as part of your network license. Each network license count is a suite license that can be used to run one of the included versions at a time.
• Delphi 7 is not available as part of the network licenses but on request you can receive one Delphi 7 serial number per license purchased.
• The Delphi 7 licenses cannot be managed via the license server or used concurrently.
