There is no specific “Free version” download. You will need to download the OpenLM Server in the OpenLM ‘Downloads’ section.
For a new installation – this will give you a 30 day evaluation period.
By the end of the evaluation period – you will be required to obtain a license file in order to keep operating the OpenLM software. Please address firstname.lastname@example.org and provide your designated MAC address and Hostname for that purpose. This license file will facilitate OpenLM features according to your purchase, or a free, minimally featured version.
