Since installing Office 2007 (over Office 2000) recently, I often encounter delays in opening Office 2000 Word files. Furthermore, I am sometimes unable to open them unless I move them to a 'trusted' directory. So I defined a trusted directory, moved the file(s) there, and can work. But when I just now tried to open an Office 2000 Word file, I received a different error message, namely ' You are attempting to open a file type that is blocked by your registry policy setting.', with instructions to disable the restriction via regedit. When I looked at the registry data, there was no 'Office' tab whatsoever under the Microsoft tab beneath Policies. So I'm unable to edit the registry to 'unblock' access to such legacy files. If someone can instruct me about what to do, I'd be very appreciative. Thanks.
