I'm pasting what they told me to do with the registry below:

Import the Jet registry key from a working computer. The following registry
key can be exported from a computer that is not exhibiting the problem (a
“good” computer) and imported to a computer that is exhibiting the
problem.
This will correct the issue. As always, great care should be taken when
working with the Windows registry, as some changes could render Windows
unusable. Both machines need to have the same OS and the “good” machine
should have Office 2003 SP2 installed and working properly (i.e. Access
launches normally). If a “good” computer does not currently exist, once
can
be created by installing Office 2003 from a CD, or another source other than
a user policy, and then patched to the SP2 level.

I'm more optimistic and hope a hotfix will be available shortly. They have
to get this problem solved because they're going to get hammered on it if
they don't. My history with them is hard to understand. Sometimes I get a
hotfix very easily and quickly; othertimes, I beg for one to solve a problem
that seriously affects me and I am totally ignored.

It's not come through, can you please post the reg key again (try plain text,
looks like you've pasted an HTML page).

If it's just a reg key, I can easily fix it. I suspect it's either missing
from the MSI or is not set to always install.
