Artist 11 - eLicenser is too old

Hello. I have not turned on Artist 11 for fifteen months. I am being told the current version of the eLicenser is too old. Could someone please guide me through the process of downloading the current eLicenser Control software. Total newbie.
Tony.

You can download the latest installer from this page:

They sent out an email late last year too about the Download Assistant:

Update to latest Steinberg Download Assistant!

From 8 AM UTC on Wednesday, November 22, 2023, the Steinberg Download Assistant (SDA) up to version 1.34.3 will no longer connect to our servers.

A new SDA (version 1.35.x) is available, which will automatically install by starting your current version until 8 AM UTC on Wednesday. Otherwise, please download the new version manually below. We sincerely apologize for any inconvenience, and thank you for your patience and understanding.
