Tetra4D FAQsMost licensing, sales and troubleshooting questions can be answered below. However reach out to our support staff if you have questions beyond these topics.
I get an “Invalid License” or “Already Activated” error message when entering my license.
Those messages can occur for 2 reasons. Either you are trying to activate a license that is already used in another device, or your system does not allow you to activate your license with the online procedure.
In the first case please deactivate your license on your previous computer in order free it for your new installation. If you do not have access to your old device anymore, please contact our Support Team with your license number.
In the second case, please switch to the offline activation procedure as explained in the Installation Guide on our documentation page. Once the .req file generated, please send it to our Support Team so we can send you back a .license file and manually activate your license.
Tetra4D is asking for my serial number even though I already activated it.
This issue mainly occurs on a laptop when you switch networks or replace a hardware component. When activating your license, the software will randomly choose a Mac Address to be tied with, and it often picks the address of your network device. When you switch networks, the license will not recognize the new one.
To avoid this situation please proceed to the offline activation mode explained in the Installation Guide on our documentation page. This will force your license to be tied with your PC’s Mac Address.
If the issue persists, please see our topic “Tetra4D asks for my license number every time I open Acrobat.”
How can I verify the status of my license?
You can check your license status directly in the “License Manager.” Open Acrobat, search your Tetra4D product in the menu bar and click on “License Manager.” A window will open and display your registered products, the serial numbers, the versions, and the status. Status Unlimited means that your license is currently activated.
You can also find the license manager in your file path at “C:\Program Files (x86)\Tetra4D License Manager v2”, then open the “RegistrationUtility.exe”.
Tetra4D asks for my license number every time I open Adobe Acrobat Pro.
First, please try the offline activation procedure explained in the Installation Guide on our documentation page. If the issue persists, please read the notes below.
You are facing a known problem where your license is correctly activated but Tetra4D asks for your serial number every time you open Acrobat. This issue only occurs with Adobe Acrobat Pro® Continuous Release.

I am on an older version of Tetra4D Converter, how do I upgrade my license?
In order to run the latest version of our Tetra4D Converter software (2021) you must have an active maintenance contract. To check the status of your maintenance contract please access “All Maintenance contracts” in your customer portal.
If you purchased through a reseller and have questions regarding your contract or need to upgrade, contact your reseller for assistance.
Otherwise, you will be able to upgrade your license by yourself in the section “License Keys Available for Upgrade to 2021”. If you face difficulties or need more details, please contact our Support Team.
Can I activate my license on multiple devices at a time?
A license is tied to a Mac Address and it cannot be activated on multiple computers at a time, unless you have bought a serial key with multiple activations. In this case we advise to keep track of your Mac Addresses associated to this key. If one of your computers is out of order, you might want to contact us with your serial key and the concerned Mac Address to deactivate the corresponding token.
I have an active maintenance contract – where are my license keys?
If you have an active maintenance contract, you should have received serial numbers and instructions on how to activate the software. If you did not receive this email, please login to your customer portal and access the Available License Keys section to see a list of your serial numbers. If you do not see your serial numbers, please submit a request to our Support Team.
Is my license compatible with every Tetra4D products / versions?
No. A license is tied to a specific version. If you want to use a Tetra4D 2021 product, you need a 2021 serial key. Please note that you need an active maintenance contract in order to upgrade your keys to the latest version.
