From the FAQ:
”A dongle is the name mostly used for USB-key protection device. There are two protection dongles, iLok from PACE AntiPiracy (iLok 1,2&3 iLok device) and USB-eLicenser from Steinberg
We provide our plug-in for both of these protection format. Only iLok is allowing a soft-base protection (meaning authorise a computer instead of an iLok device).”
so looks as if you can use iLok to authorize it on your computer if you don’t have a hardware dongle.
