Starting with IDS v15.1.0, Adobe no longer provides serial numbers for IDS installations. Instead, licensed users download a package file with the license included with the IDS software.
Datalogics is responsible for creating this package file, Windows (zip) and macOS (dmg). Users will download this package file from Datalogics FTP servers.

NOTE: When you install the IDS software using feature restricted licensing and activation, you must have an Internet connection to validate the product license.
For older versions of the IDS software, Datalogics provides the licensed user with a 16 digit serial number.
The user then downloads a trial (watermarked) version of IDS from the InDesign Server Trial Downloads Program page:
and use the serial number provided to activate IDS.
Activating IDS using the serial number removes the watermark from the trial version.
Instructions on how to activate the software using a serial number can be found here:
