Importing License Response Files for an OEM application license
 | TwinCAT 3 licenses for non-Beckhoff IPCs If you use an IPC from a manufacturer other than Beckhoff (TwinCAT 3 platform level >= 90), a TwinCAT 3 license dongle is always required for licensing TwinCAT 3. |
| TwinCAT root directory <TwinCAT_ROOT> Up to and including TwinCAT 3.1.4024: C:\TwinCAT |
The OEM application license is activated in the same way as a standard TwinCAT 3 license. The simplest way to activate a TwinCAT 3 License Response file in TwinCAT 3 is to import it via the TwinCAT 3 license manager. Further information can be found in the “Licensing” documentation in the section Importing and activating a License Response File.
However, you can also save the license file directly on the target system in the directory <TwinCAT_ROOT>3.1\target\license.
The procedure to save the license file on a TwinCAT 3 dongle is described in the documentation "Licensing" in the section Saving license files manually on the dongle.
