Publisher 07 can't open older publisher documents

[Sid]

I've just installed Publisher 2007 but can't open years of work created on
older publixher versions. An error message says that publisher no longer
supports files created in older versions of itself. Is there a way I can
open those documents?

I don't know why this is happening. I suspect a security update. I've had
several folks email me personally with this situation. One poster sent me two
2000 files that I opened in Publisher 2000, saved and then I could open them in
2007. I could not open the files in 2007 before hand.

Might try the instructions in this article:
Error message when you try to open a publication in Publisher: "Publisher cannot
open the file" or "Publisher has detected a problem"

Do you have the older versions of Publisher installed?

I do not have any older versions installed, and either lost/discarded or
never had discs of the older publisher versions. I'll try your instructions.
Thanks.
