Before installing the license file, save a backup copy in a safe place.
The Keysight License Manager (KLM) software requires a LAN connection between the PC on which it is installed and the instrument-controlling PC. It can also be installed directly on the instrument-controlling PC.
If you do not have KLM installed on your PC, you can download it at no charge from the following website: http://www.keysight.com/find/licensemanager.
Copy the license file to your PC. The license file has a .lic extension, and is attached to the email message you received when you redeemed your license.
Obtain the hostname or IP address of the controlling PC.
Use the KLM software to install the license file on the controlling PC. Refer to the KLM help for specific instructions.
