:
How do you upgrade from Premium to Ultimate if the Premium version number is
newer than the Ultimate version number? When I try the upgrade to the
Ultimate DVD, the install says that the Premium install is a "newer operating
system" and then only allows a clean install, which isn't much fun. Is there
any way to tell the install to ignore the version numbers and just do it?
