Licensing
To use the octoplant system, you need a valid license. The licensing process can be summarized as follows:

All octoplant license files are temporary and must be activated to extend the license for the full duration of the subscription agreement. Each license includes an expiration date and a renewal date.
- Expiration date: Indicates how long the license can be used for the installation. The license must be activated before this date.
- Renewal date: Defines the term of the subscription.
To remind you about the licens expiration and the need for revewal, several warnings appear in your system:
- 90 and 60 days before the expiration date: A notification appears when you sign in to the AdminClient, indicating that the license will expire soon.
- Starting 30 days before the expiration date: A corresponding message appears in all clients during sign-in.
- After the expiration date: The license remains valid for a 7-day grace period. During this time, a warning appears in all clients.
- From the 8th day after expiration: You can open only the Licensing dialog in the AdminClient.
Info
- If the maximum number of clients you have ordered has been reached, you will need a new license.
Displaying license information
To view information about your license, including the expiration date of subscription and the renewal date, you have two options:
- Open the license JSON file with any text editor, like Notepad++.
- Open the Information tab of the Licensing dialog.

Activating a license
Info
Generally, octoplant must be activated within 30 days after receiving the license. The period depends on the expiration date specified in the license.
After successful installation and configuration of your octoplant system, proceed as follows to active the license:
-
Open the Activation tab of the Licensing dialog. The Activation tab shows the system ID of your octoplant system. It is created on your server and is unique for your installation.

-
Send the system ID to AMDT via the myAMDT portal by creating a support ticket under Open new Service Request > License and contracts. In return, you will receive the activation code for your license.
- Copy the activation code into the Activation code field.
- Select the Activate button. Your license will be activated.
Note
-
The recommended way to send your system ID to AMDT is via the myAMDT portal by creating a support ticket. Using the Send by email option will also create a ticket. However, to ensure efficient processing and avoid unnecessary ticket duplication, use the myAMDT portal whenever possible.
-
If you have questions regarding licensing and activation, submit a support ticket via the myAMDT portal.
Reactivating a license
You need to reactivate the license if any of the following changes occur:
- MAC addresses of network adapters (can be deactivated via license key)
- Windows Product ID
- Installed graphics adapters (if present)
- Computer name and domain
Updating the license file after renewal or upgrade
If the serial number of a license has changed, you need to update the new license file.
- Download the license from the myAMDT portal > my Products > License Overview.
- Open the AdminClient and the tab Update.
- Enter the path to the license file or select the file location from the dropdown menu.
- Select the Update button. Your license will be updated.
After updating the license
- Activate the new license.

FAQ
Licensing with an unused license file shows error message
Situation: Some time ago I requested and received a license file (license.json). The file was saved correctly, but remained unused for some time. When I try to relicense using the file in question, an error message is now displayed stating that the selected license has expired.
The license file has expired. Each license file has a fixed expiration date and can be used from the day it was generated until this period expires. If this period has expired without the license being activated, the license file becomes unusable, i.e. it is no longer possible to install with this file or to import the license into octoplant. To reactivate your applications, request a new license file via myAMDT portal.
