You're going to need to download and install the one Adobe has made available online anyway, since if you could install from your CD you'd never get it activated. Your discs are essentially useless now.
Follow the instructions here and use the serial number they provide.
I just purchased a new lap top and want to load Photoshop CS2 on this computer.
Before you try, check the system requirements.
If your new laptop is an Intel-based Mac then you won't be able to install CS2 since that was written for the outdated PowerPC Macs and there's no compatibility between the two.
