Oem word 2000 and office 2000 with vista

[Fiery_WA]

Gday

I have just purchased a laptop with vista hp on it. It has come with a trial version of office.

I have an oem word 2000 disk and own a copy of office 2000.

First question, will vista recognise and end up shutting down my oem word?
Second question .. I know this one sounds dumb but better to ask .... Do I need to uninstall the trial version first?

Cheers

Susan
