Office97 Regional Settings Problems…..

By accident i have installed Office 97 on a clients notebook when the regional settings in win98SE were set to US. I have tryed to uninstall Office and change the regional settings to Australian and then re-install Office. But Office setup never asks me to choose the Australian dictonary. I am using Office97sr2a and it has always asked me to choose my dictionary in other installs. PLEASE HELP as i have 4 notebooks all with the same problem.
