Microsoft Jet OLEDB 4.0 STILL not working on 64-Bit?

Question

I've seen all the posts (hundreds of them) concerning the fact that the Microsoft Jet OLEDB 4.0 provider only works on 32-Bit systems.  Really?  I'm running Windows Server 2008 Data Center and have an urgent need to run an SQL Job that needs to query an Access database.  The job runs DTExec to execute an SSIS package (the Job step is configured with the "Use 32 bit runtime" checked (set to true)).  I am getting the follwing error message when I'm on the part of the SSIS package, which is an 'Execute SQL Task', which attempts to open the Access Database: 
DTExec: The package execution returned DTSER_FAILURE (1).

I find it highly ridiculous that Microsoft would not care to release a 64-bit driver for Jet OleDb 4.0.  There is obviously a need, judging by the hundreds of posts out there with people asking about this.
Or am I missing something?  Is there a driver that I just can't find?
Thanks.

The Jet OLEDB provider consists of several dlls. You can check if these dlls are installed.
For x64 machines, the 32-bit folder where I expect they live is C:\Windows\Syswow64 or C:\Winnt\Syswow64
This list (taken from http://support.microsoft.com/kb/278604) seems to cover the Jet dlls:
Microsoft Jet 4.0 OLE DB Provider
Provider=Microsoft.Jet.OLEDB.4.0
C:\WINNT\System32\Msjetoledb40.dll
C:\WINNT\System32\Msjet40.dll
C:\WINNT\System32\Mswstr10.dll
C:\WINNT\System32\Msjter40.dll
C:\WINNT\System32\Msjint40.dll
This article tells how to see if Jet is installed, and which version is installed, and how to get the latest service pack 8 http://support.microsoft.com/kb/239114/
However, that kb 239114 it says "For computers that are running Windows Server 2008"
If you are running Windows Server 2008, you have a later version of Jet 4.0 than the version that is included with Jet 4.0 SP8.
If you don't find Jet is installed correctly, I am not totally sure what to do - sounds like Windows is not installed completely, or the feature was not enabled in the add/remove windows components.
Indeed Jet is only 32-bit as Todd mentioned http://support.microsoft.com/kb/957570
Since Jet is included with the OS I expect the install to have been done by one of the *.inf files in the C:\Windows\inf. I found several inf files on my Win 7 machine (not a good comparison for you) which cover these dlls such as (syssetup.inf, layout.inf, oem33.inf). I know it is possible to right click and run the install on these .inf files, but since its a windows component, it would be reinstalling windows components too, which I would recommend against on a production server, escpecially a datacenter edition! Must be a high end production server, so I can't recommend you do that because I'm afraid it would break something else because I haven't tested it before.
Let us know if you find the dlls or not.
