It appears that some Read-Write CD Drives don't work quite right when trying to install Delphi. They may takse an unusually long time to install, with the CD-ROM 'clicking' as it does a reading-stopping-reading process. There is a known problem with HyVal IDE drive causing this problem. The solution is to install a new driver for the RW-CD that hopefully doesn't have the problem. Or, you can try installing from a traditional CD-ROM drive instead of the RW-Drive. If you are on a network, another alternative is to 'Map' someone else's CD-ROM drive and install Delphi from this mapped drive.
