MATLAB: How to change the activation of a MATLAB installation from Individual or Designated Computer to Concurrent

We have several computers with a Designated Computer activation and recently obtained a new Network Concurrent license. How can I switch the current activation of MATLAB to Network Concurrent?

Best Answer

Before MATLAB clients are able to check out a license key from the license server with the Network Concurrent license, make sure that the License Manager is installed. Please see here for instructions:

Once the License Manager is installed, copy the license.dat from the server (by default located in $MATLABROOT/etc, e.g. C:\Program Files\MATLAB\R2019b\etc) to a folder on the clients.
Deactivate MATLAB:
As a next step, remove the old license activation from the MATLAB installations. For instructions, see the following article:

Re-activate MATLAB:
After the deactivation is complete, launch MATLAB. It will ask for a new activation. In the Activation programme, select ‘Activate manually without Internet’. Proceed with the steps. When prompted for the license file, point to the license.dat file. MATLAB should now use the Network Concurrent license.
