Under normal circumstances a single user licence for CIRCLY, HIPAVE or APSDS requires you to use a Hardware Lock (aka "Sentinel" or "Dongle"). 

The PC that you are sitting in front of must be running CIRCLY, HIPAVE or APSDS and the Hardware Lock must be plugged in to that PC.

For security reasons we do not permit you to run CIRCLY, HIPAVE or APSDS remotely via a remote client such as Remote Desktop, Terminal Server, VNC or WinXP remote client.
