Is there any help for my question?
First, this is a user to user forum; no Adobe personnel is asigned to answer questions here and so you cannot expect instant answers. Second, you can try your luck here: Find your serial number quickly. Third, if you happen to be lucky in recovering your serial number, I very much doubt that you can successfully install such an old program under any modern OS (and it is simply impossible to install it under any Mac OS not capable of running in Classic mode).
On a worst case scenario there should still be a 30 day trail version of pagemaker available on this site,
Scratch that, the download links seem to be broken, Hopefully it just a temporary thing. You will need an older computer to run it, one that runs OS9 or classic on the mac and Windows XP on the PC
Indesign CS6 will open most pagemaker files the conversion can range from flawless to unusable.
