Is there anything else I can try short of archive and install? And if
that's my solution, what Apple updates should I install after
reinstalling the OS to make sure this doesn't happen?
An "Archive & Install" isn't so bad, just be sure to check "Preserve Users
and Network Settings" when you select Archive & Install.
After you do an "Archive & Install" you are back to the original OS X
install version. Apply the combo updater and restart. Repair permissions.
Next run Software Updater and it will get any updates since the combo was
posted.
The problem happened because files were corrupted along the way. There is no
way to stop it from happening again, but there are easier ways to deal with
it. You need backup software. I use "SuperDuper!" along with many users on
this newsgroup and other Mac lists

One of the features of "SuperDuper!" is what the author calls a Sandbox in
addition to making a bootable clone on your HD.
A Sandbox is a bootable copy of your system, stored on another hard drive or
partition, that shares your personal documents and data with the original.
With SuperDuper!, you actually use the Sandbox as your startup volume. You
can safely install any system updates, drivers or programs in the Sandbox,
without worrying about what might happen to your system. If anything goes
wrong, you can simply start up from the original system. SuperDuper! has
preserved it in its original, pre-disaster state but all your new and
changed personal documents are totally up to date. Within minutes, you're up
and running again without having to go through a difficult and
time-consuming restore process.
This way you can take your time working on your problem. It seems that
update problems have become more frequent for both the OS and applications
Just a fan of SuperDuper!
