Yes, I think so. I remember Hi-Soft selling manuals and stuff in one of mags. You had to call them to get the licence key to run the CUCD.
Releasing the licence number became an issue in some quarters. People who left it too late were disappointed to find Hi-Soft closed down and their disk unusable. It may be a matter of opinion, but I think since they published the CD, anyone with a legal copy should have access to the licence key. CUA simply forgot to publish it in the mag, they admitted that and quoted a phone number to call. That lasted a few weeks and then went dead.
The CUCD installer was also faulty! It wouldn't work at all. Amiga Format subsequently included a revised installer for the CUCD which had the licence number built in. That was in AFCD35 (January 1999).
