I am just about at the end of my rope with SETUP.

I have checked and rechecked that I am doing everything according to the manual but the setup disk reports that there is a problem. It says "Object 19 Your setup files may be damaged. Try restarting the Setup program from where you originally ran it"

I am running Visual Suite with the service pack installed.

Am I missing some patch or patches? Has anyone had this before?
Any idea what I have done wrong?
