As Plexus Connect uses the Instant JChem desktop application as an administrator tool, you will require an Instant JChem Enterprise license as well. Furthermore, if you want to use the default Marvin JS editor within Plexus Connect, you will need a Marvin JS license as well.
If you would like to require a license for Plexus Connect or need some help with handling the licence file, please, consult our sales team (sales [at] chemaxon [dot] com).
