|Lotus 123? You can always burn floppy contents to a cd but for multiple floppies running a setup from the cd may not work if it was intended as a floppy install.|
There should be an install.ini file on the first disk that tells install.exe what to do. You may be able to edit that .ini file for a cd install.

I believe that references a different version than you have but Toolman59 says you can just copy the floppy contents to a cd but you have to make sure you copy the hidden file.
