I have just installed Office 2007 on same machine as 2003. All works as expected except for Access. Microsoft installer runs when switching from one version of Access to the other. Not only annoying, but time consuming. The only "solution" offered, that I could find, was Microsoft's suggestion to install SP2 (done), which is touted to speed up the installer, but not fix problem. Has anyone come up with a better solution to this problem? Thanks,
