You install programs exactly the same way you did the 1st time... put your disc in the drive and enter your serial number when asked

Lost information - see reply #1 in https://forums.adobe.com/thread/2008767
- page has links to programs to find an installed serial number in Mac or Windows
- includes link to your Adobe account to check for registered serial numbers
- when you find your serial number(s) write them down and put in a desk drawer
Mac or Windows, and EXACTLY which version of the operating system?
Recent Mac AND Windows operating systems have been known to not work with old programs
