I've been offered a Quark XPress 7 Upgrade (proper upgrade box). I am running 6.5 at the moment, all above board and registered.

Question is, will I be able to upgrade to 7 using an upgrade that someone else has bought or does it require it's own registration details to match the buyers older version?

I'm only upgrading to produce one job, then I'm looking to move to InDesign CS4 so i don't want the expense of buying an 8 upgrade.

Thanks, in advance.
