License Key - Current User vs. Local System

If SmartFTP has been installed/registered, is it supposed to be linked to the user key vs. the local system?

i.e. if someone else logs into the machine it says that smartFTP is expired and won't run.

SmartFTP is licensed per user/person. If 10 user are using SmartFTP you need a multi user license for 10 users. Please contact our sales department ( to add additional users to your existing single user license.
