Omixon HLA Twin and Explore use the machine id file, to generate a hardware key – a unique machine identifier for the Omixon application. The file must be accessible in /var/lib/dbus/machine-id, and it is a randomly generated by dbus-uuidgen, typically invoked by the post-install script of a D-Bus package. It can also be a symlink to /etc/machine-id, but the file has to be present in either way on the path above. In some Red-Hat distributions this path does not exist.
To fix it, run
$ dbus-uuidgen > /var/lib/dbus/machine-id
If you don’t have dbus-uuidgen , it’s in the dbus package, which can be installed by issuing
$ yum install dbus .

Start up the software and go to Application Settings. Use the “Display Hardware key” option available in the left hand “Administration” menu to display the hardware key. Since certain letters are indistinguishable based on a screenshot – for example “l” and “I” – we strongly recommend using the “Copy to clipboard” option available on the popup window which copies the hardware key to the clipboard from where you can easily paste it into an email.

You will receive an Omixon license by email. You can right click on the link from which the license is available for download and use the “Save link as..” option to save the license to a suitable location. Please make sure that the license has a “.lic” extension and is not saved as a txt file. If it has been saved as a “txt” or as a “lic.txt” please rename it to have a “.lic” extension.
