To use a network license of ARES Commander you need an additional Graebert Network License Manager (NLM). This NLM can be run as separate program or as service and it administrates the network license(s).
To get a download link to the current NLM version, please contact [email protected].
For ARES Commander 2017 (and newer versions) you have to follow the steps shown in the NLM-Dialog of "Licenses-->Request License...". Here you can activate your network license on your own via the Graebert Customer Portal.
Attached is a PDF-document that explains the installation and activation of network licenses.
