How can I install my Adobe Photoshop on my computer with Windows XP Service Pack 3?

How can I install my Adobe Photoshop on my computer with Windows XP Service Pack 3?  Seriously frustrated.  I put the disc in the drive and nothing happens.  I open up add/remove programs and I get an error message stating it can't find a disc.  I chatted with Adobe support, and they decided to send me here. Probably because they knew I wanted to spend all day online trying to figure this out.
