How to use two licences in a single virtual machine?

I want to use two Unattended licences in a single virtual machine (with users A and B) so that the licences can be executed simultaneously.
Apparently I managed to do it on the Orchestrator but when executing processes in both licences, an error message is shown:
Is there any setting I must adjust to let it run properly?
Thanks in advance.
