Access 97 error "unable to initialize the windows registry"

We unfortunately still require the use of Access 97 - so we have it installed
alongside Office 2003. However, we want our users to be non-admins on their
computers. Unfortunately, if they are in the Users group, Access will not run
properly after opening Access 2003. The error when opening Access 97 is:

"was unable to initialize the windows registry" "rerun Microsoft Access or
Microsoft office setup to reinstall".

Once I log on as an administrator and open Access 97, it runs fine until the
next time this pops up.

What do I need to do in order to make Access 97 work with a "User" account
in this environment? Are there some registry permissions I need to change or
something?

TIA
