If BASE license is used by itself, it will be shown as non-active license like shown on the picture below:

To activate the BASE license, Dewesoft requires an additional Professional license (or any other bundle license) to be active at the same time.

For example we have used the BASE license with Order tracking option on USB dongle. 

If we also connect the Sirius slice which has the default PROFESSIONAL + CAN license, the BASE license will become active.

Now we can use all the options of the of PROFESSIONAL and BASE license.
