I'd rather not use regedit to fix that myself. I have the same problem, I have EU:Rome Gold which I got from gamersgate and the patcher won't work because it sees I haven't got Vae Victis (which I do obviously as I have Rome Gold and I have tried the beta patches fine before this).
EDIT: The same problem as described in the first post that is.
