Jet can run on Windows XP x64 for example, but in 32-bits mode.
There is only a 32-bits version of this driver.
"The Jet Database Engine will remain 32-bit only for the
forseeable future. Microsoft has no plans to natively support Jet
under 64-bit versions of Windows. This means that native 64-bit
applications (such as the 64-bit versions of SQL Server) cannot
access data stored in MDB files through ODBC, OLE DB, or any other
means." from
http://en.wikipedia.org/wiki/Microsoft_Jet_Database_Engine
That claim is not documented by any Microsoft sources, and I wonder
if it is out of date.
The page is also incorrect in what it says about the the future of
Access/Jet:
However, Jet is and will continue to be the primary database
engine for Microsoft Access. In fact, Jet is essentially going
back to its roots with Access 2007, by being distributed (and
supported) only within Access.
This is *WRONG*. The Jet db engine now has two versions, one of
which is a Windows component maintained by the SQL Server team (the
traditional plain old Jet engine, the one used for Active Directory)
and the other maintained by the Access team, which branches from the
other version and can add new features. The citation of Eric
Rucker's blog for this claim is completely misleading -- he does not
say that Jet is now used only in Access. Instead, he says that there
are *two* versions of Jet, and the one maintained by the SQL Server
term is not being upgrade.
This is not news!
This is what we've been told since the release of Jet 4!
So, I have a problem trusting anything posted in the Wikipedia
article, as I can quickly identify inaccuracies without needing to
read more than a paragraph away from the quotation above.
(I've posted questions on both these issues on the Wikipedia talk
page and we'll see what they come up with in response)
"Jet: Starting with version 2.6, MDAC no longer contains Jet
components. In other words, MDAC 2.6, 2.7, 2.8, and all future
MDAC releases do not contain Microsoft Jet, Microsoft Jet OLE DB
Provider, or the ODBC Desktop Database Drivers." from

That last one is not even close to being news. It's been the case
for a couple of years now. And it has nothing to do with the 64-bit
issue.
