Have you had a look here?

A while ago Adobe released a whole bunch of old software and serial numbers for free download and also so you don’t bother them with re registrations etc.
I downloaded these and installed some. All worked. I didn’t install ver 3 as I had ver 6 but I do have it on DVD. Legit not pirated.
The link above was something I found which seems similar.
If the link is no good, I’ll be back home in a couple of days and can double check I still have the software and the correct version.
Hope this may help.
I’ll post my findings.
Cheers,
Damien
