I have looked on MS website and cannot find the answer. Can Access 97 be installed on a pc that has Access 2003 installed? You can with A97/A2000. Also, will an Access 97 runtime run in an Office 2003/Access 2003 environment? I have heard rumors that this will be a problem - but cannot find any documentation. MS website mentions Access 2000, 2002, 2003 compatibility - but that is all I found.
