silent install for active desktop calendar

[eltuup]

I've got Active desktop calender. I would like to install it with my unattended cd but can't find the switch.

I have version 4.5 with registration code. Is it possible to install this program (silent) with the code?

I have managed to intall this application silently with /SILENT but could not make register it automatically. Could not trace any registry entry with the registration code.

Any suggestions?
