Installing the License Key for Napatech Link-Capture™ Software

When you receive your license key, follow these steps to install it.

Make sure you have requested and received your license key for each Intel® PAC A10 GX card. See Requesting the License Key for Napatech Link-Capture™ Software for more information.

Make a backup copy of the file.
Note: This is in case you delete the entire installation directory /opt/napatech3 during re-installation or update of the Napatech Link-Capture™ Software.
Install the ntlicense.key file:
```
sudo cp ntlicense.key /opt/napatech3/config/
```
ntlicense.key is a text file that contains one or more license keys. It can contain license keys for several AFU images for the same Intel® PAC A10 GX acceleration card.

Verify the installation:

Stop ntservice and remove the /opt/napatech3/config/ntservice.ini file:

$ sudo /opt/napatech3/bin/ntstop.sh 
Stopping NTService (this may take a while)
NTService stopped                                           [Done]

$ sudo rm /opt/napatech3/config/ntservice.ini

Restart ntservice without any previous configuration to check that it now loads the selected AFU images during initialization:
```
sudo /opt/napatech3/bin/ntstart.sh
```

Check that the Intel® PAC A10 GX acceleration card is available by running this command:

/opt/napatech3/bin/adapterinfo

Here is an example of the output:
