@Barnir i have a valid ETS5 Dongle and a cracked ETS 5.7.4, the Method i use for signing cracked .knxproj files is still working:

-run the ETS cracked
-import the unsigned .knxproj
-close the ETS and “uncrack” it
-run the ETS with plugged in dongle and export it
-done

If you upload the unsigned .knxproj somewhere, i’ll sign it for you, otherwise you can provide a email address and i’ll get in touch

(@admin a PN feature would be dope btw :D)
