Recently when I tried to apply the latest Office 2008 update, it began giving me an error message during the installation process saying that I can't install it on that drive because I needed Mac OS X 10.4.9 or higher (I have the latest version of Leopard 10.5.5). I tried deleting the whole thing and reinstalling Office, but now I can't even run the installation program because it's giving me the same error message. Does anyone know how to get the installer to recognize that I have 10.5.5 and that I should be allowed to install Office on that volume.
