Hi Michael and Nick,
Here's the whole story. I left Terminal on and running since our last conversation. When I checked and saw nothing happened, I tried to launch FCS disc for installation. I got the same "no longer supported" message. Therefore, you got my "nothing happened" message earlier.
But as a habit, I thought I would give this painful and unpredictable process a second chance. So I started Terminal again. When I copied and pasted your instruction line in again, the installation suddenly occured. And bingo, this installation issue is successfully solved.
Thanks to you all. I am checking to see if the applications programs run properly. If there's any problem, you'll see me here bugging you guys again.
