Go into the folder where the Access 97 msaccess.exe is located, and look for
two files named msaccess.srg and wizard.srg. Rename them, then create two
empty files with the same name.
Access 97 won't be quite as aggressive about reregistering itself each time
you run it after that. However, I believe the default will still be that
when you click on an MDB file, Windows will try and open it with whichever
version of Access was opened last.
