Setupx was setupx.dll, not setupx.exe as mentioned in the link "inthewildteam" gave. I took 2 actions...renamed setupx.dll to setupx.dl_ to and rebooted, AND restored original setupx.dll from CD. Neither option had any effect. Also I scanned with Avast
which should have detected an infection. Virus infection extremely improbable as it was as clean install on a private network behind firewall.
In any case, it's out of my hands now since the friend I set up the computer for has taken it home now.
Again, many thanks for all who contributed their thoughts
