Osx Install Problem, no suitable drive found Options

[Chris C.L]

Just downloaded OS10.3.9. Curently running 10.3.7.
During the select destination process I click on system drive and get-
You cannot install this software on this volume.This voulume does not meet the requirements for this update.
Thought the only requirements were OS10.
Ages ago tried updating appleworks+stuffit but installer could not find original programs. Weard huh
