Hello @AndhikaDwi,
The trail versions are for evaluation purposes only and are not meant for production use. If you got one single key for all the 4 products & an Orchestrator is not involved, this would mean that you will have to use all the 4 products on a single machine. That said for period of 60 Days you can build using any edition of the studio & publish the workflow, then run it from the Attenuated Robot.
Hope that helps ! Kudos 
Thanks & Regards,
Nithin
