there is a major problem with eplan 2.2 and all dongle emulation tricks.
They rewrote the complete HASP Interface, and there is a hoax message included.(yes, 2.2 only works with the latest)
If you are lucky, you will get it work for 30 days, but "DO NOT CALL THE HOTLINE IF YOU GET THIS ERROR:"
here in german:
After that message Eplan starts without any problems.Aufgrund eines Hardwarekonfliktes kann EPLAN auf Ihrem System nur mit eingeschräkter Leistung ausgeführt werden.
[Fehler: 4521]
Bitte wenden Sie sich zur Lösungen dieses Problems an Ihren Händler.
Error: 4521 means "Dongle Emulation found".
So if you reproduce your original dongle to a software dongle plz don't call the hotline before anyone has a solution for that.
