We want install hotfix 1033 for ArchiCAD 11 in silent (unattended) mode. The parameter "-w play.auto=YES" is in this hotfix not supported. Know anywhere a parameter we can use.
I just tried this on Intel MAC and PC for being sure that it works. If you follow the steps described on this link you should be able to run it in silent mode:
The silent hotfix installation changed from AC 10 to AC 11. The AC 11 hotfix will install itself silently but the finish panel will be left there for showing that an install was performed.
If it still does not work please submit the details of the problem (screenshots are welcome too).
