The Load Balancer asks for your license key upon installation. If you wish to use a newer license key (for example, moving from an evaluation to a full license, or if your licensed IP address changes), you will need to manually replace the license file.
The file is located at ZEUSHOME/balancer/etc/licence.key (Note the spelling!), which is found inside the directory where the balancer was installed (typically /usr/local/zeus). The file should contain just one line of text, which contains your license key - with all the spaces removed. For example, if your new license key is '1234 5678 9012 ABCD EFGH', the file should contain just the line:
123456789012ABCDEFGH
After editing the file, you can then restart the Load Balancer to check that the new license is OK.
