unable to re-install arcsoft showbiz program by application recove

I had problem with the prog arcsoft showbiz v 2.0.0 so removed by the
add/remove progs.It came bundled with my pc.I tried to re-install using the
compaq application recovery but when it got half way through a window came up
saying ....an installation support file could not be installed. the system
cannot find the file specified.... The program icon came back on my desktop
but when i clicked on it another window came up which read......You have
modified program settings file. showbiz failed to launch....(I don't know how
I would get to the program settings) I don't know how this has happened as I
used the correct procedure.I did a system restore but to no avail. Pc world
helpline cannot help me..
