You are talking about very ancient software; PageMaker has been an officially dead program for several years now. Not even PM 6.5 is supported under XP; you were extremely lucky if you managed to use 5.0 before. I would be surprised if you succeeded in installing it once more, and to function faultessly.
I need help installing PM 50.0a on windows xp. Had it installed on xp before computer crashed. Having trouble installing it back on anoither xp comp.
Just forget it. Or get a Windows 3.1 PC.
I got it installed. Thanks for your "words of wisdom"
