The USB HASP dongle is required for the copy protection of the software.

Each dongle can be programmed for a single license of each program. For instance, dongle 1 can accomodate River Flow (1 license) and Sewer Networks (1 license). If you need a second license of Sewer Networks, this must be programmed into another dongle (dongle 2).

If you are an existing user, it is possible that you do not require a new dongle.

It is possible to divide your purchased programs into more dongles, so that they run simultaneously on different computers.

If you are uncertain, please contact TechnoLogismiki prior to your purchase.
