I have the disk to download Adobe Photoshop CS2 but i dont have a CD-ROM on my laptop, is there any way i can get it on without a CD-ROM?

CS2 (and earlier) Activation Server is gone, so read below

You MUST use the special number on the page, not your original serial number

NOTE that CS2 will not install at all on a "modern" Mac, and when you install the special version of PPro2 on a Win7 or Win8 or Win10 computer, you MAY need to right click the program icon and select WinXP compatibility from the option popup
