Original CS Ver. 1.1.1 not supported. customer Service provided link to CS2 download. Download prompts for installation disk.

As a courtesy Adobe Support forwarded a CS2 download link w/Serial # to replace my no longer available original CS Ver. 1.1.1 softward I purchased as a student 11 years ago. The download went fine but when I was installing the download, the installer prompted me for my Installation Disk#2. I tried inserting my Ver. 1.1.1 disk but it was not recognized. Any suggestions?
