vik01's remark below doesn't make sense.
"I have a new disk 4 installed in the cd."
"But a get a message to insert the FS2004 Disc $, sleect OK and restart application. ....."
From the above statement - we can assume that FS9 is installed (I think)- hence the prompt to insert Disk 4 - if he doesn't insert the Disk 4 in the CD ROM then he will get no joy
"I can see the disk 4 contents in the explorer, I don't understand"
vik01 has somehow copied Disk 4 files into his hard disk - why? I hesitate to guess and obviously thinks that because he has a presentation of the CD 4 on his hard disk that he does not need to insert the Disk 4.
It all begs the question.
Has he read the installation instructions?
As it is unlikely that vik01 will return, I do feel sorry for hooktail as he will miss the entertainment - but as they say - 50% of the us try to help - the other 50% stand and watch.
