We added support for Cloud-based licensing with SD7.2 and from that point began phasing out USB dongles.

Stardraw Design 7.4 does not support dongle-based licensing but it is simple to switch over to Cloud-based licensing, and there is no cost to you; simply email techsupport@stardraw.com and we will switch your license to the Cloud so you can enjoy the many benefits this modern licensing system offers (not least, that you don't have to remember to bring a dongle while travelling!).
