Trouble Installing/Updating Apps via CD

[Mark Sargent]

Hi All,

I'm wanting to install the Development Tools pkg via FC3 install Cds, 
and do the following,

1. Run Add or Remove Packages
2. Check the pkg wanted
3. Then install and mount the CD asked for, but, get the following error,

:::::
Unable to access disk.

The disk was unable to be accessed for reading.  Please confirm that it 
is in the drive and try again.
:::::

even though the CD icon appears on the desktop, and I can open the CD in 
a window. What can I try here..? Cheers.
