Office2000 & Office97 on NT workstation

I need to install Office 2000 & Office 97 on an NT4 workstation. I need Office 97 to be the default application as all the other users on the Network use Office 97. I know that you can save back Office documents, but its mostly Acces 2000 I will be using and I don’t want to have to convert databases so that other users cant use them. Thanks.
