How to change installation location from a Creative Suite 6 CD

A while back I had installed the Adobe Creative Suite 6 on my desktop and mostly ran the Adobe Acrobat X program, which I loved. I had originally installed those programs on a drive other than the C: drive because I was running out of space. Recently that alternate drive started to have data integrity issues and I replaced it. The computer tech mapped the new hard drive to another location. Initially I ran a repair utility and Acrobat worked again. Today Acrobat refused to even start and even the repair utility isn't working. I uninstalled Acrobat and then tried to re-install it from the original CD, which would work fine IF the CD allowed me to change the installation location. It's still pointing to a non-existent drive and does not allow me to change the location for installation. Any ideas about where the CD gets this info and how I might be able to change it?

I also tried downloading the file from the Adobe website and after wasting a lot of time and data, it told me my product key was invalid. It's definitely not invalid since the original CD autofills the same number.

Thanks in advance for any suggestions. I'm pulling my hair out over this one.

Thanks,

Cathy
