I think there are much misundstanding between the USB dongle and Disk version.
There are two ways to register ZWCAD stand-alone.
1. USB dongle.
You only need to use the USB dongle and the suited license code. The USB dongle decide the different between Standard and Professional.
2. Disk license.
The disk license only have the license code. And it is difficult to tell the different between Standard and Professional with one license code.
So, we have two license, one for ZWCAD (Standard), one for ACIS (3D functions).
If you have the USB dongle and the suited license, so you don’t need the ACIS-code.
ACIS-code is an old register method for ZWCAD. Now ZWCAD doesn’t support ACIS-code for register, you can choose dongle or softkey to activate your purchase.
