Or does the last update contain everything in the earlier patches?
I just recently installed ID CS4, and haven't had much chance to work with it. However, I think I only applied two of the six or so updates available for it, including the last one. I'm guessing I can't go back and add, say, the 6_0_3 patch after having already applied the 6_0_6 patch.
Assuming I need to apply them all in order, do I have to deauthorize, uninstall, reinstall and then apply the patches in order?
Updates are cumulative.
Thanks! I wasn't eager to re-do the installation.
