If you want to monitor remote computer activity, than you need to download a license into application while installation. License is available for employer just after project creation.
While installation a license request will appear. You need to put a file path and finish installation.
Note, that if you install application for employee monitoring, than you need to pass this step. In that case license will be downloaded separately.
After you finish installation, all further work of the computer will be tracked into employer reports. Monitoring will be stopped only after switching off. All activity at said computer will be in operation reports.
