Question : Could not find installable ISAM, sql server 2005, SP3

I'm getting  
OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "(null)" returned message "Could not find installable ISAM.".
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "(null)".

when running the following statement:

INSERT INTO OPENROWSET ('Microsoft.Jet.OLEDB.4.0'
, 'Excel 8.0;Database=E:\directory\ShopCheckOff2.XLS'
, 'SELECT * FROM [Sheet1$]')SELECT * FROM [tblXLSReceipt]

Everyting I've looked at, based on Experts Exchange and MS support, etc all seem to be in line.
OS:  Win Server 2003 SP2 x64
SQL Server 2005: 9.00.4035.00      SP3      Express Edition with Advanced Services
(running in the program files (x86) directory)
MDAC 2.8 for win server 2003
Jet 4.0 win server 2003 SP2

This code works at other installations.  So it's environmental here, but I'm completely stumped as to where the issue might be.  

I'm at a client site doing an installation and planning on training, and this has just totally bollocksed me up.  Any quick responses would be fantastic.

The reason behind error is that there is no 64 bit provider for Jet Providers.
