"Recovering" My Copy of Tekton MM

I own a legal copy of the Tekton Multiple Master. It came bundled with my original copy of ATM 4.0, which worked fine when I was using Windows NT/2000. The OS on my current home PC is XP. When I try to install Tekton using the built-in Windows Font Installer, no fonts are recognized on the ATM CD. Is there some way to "recover" (uncover?) a usable copy of Tekton from this CD? It's one of my favorite fonts, but I can't afford to replace it. Any help would be greatly appreciated. I have a feeling I know the answer, but have to ask it anyway.

Thanks!
