64bit ACE 12.0 - "Could not find installable ISAM"

Question

Hi!
I want to use openrowset to read a table or two from an excel file..
Im getting this "Could not find installable ISAM" error and after trawling the forums for days I haven't found any solutions that work for me..
Here's my query:
SELECT * FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0','Excel 14.0;Database=E:\Project Data\339_IMP\Code_labels_latest_Sep09_breakdown.xls', 'SELECT * FROM [loftins$]')
And here's the error message:
OLE DB provider "Microsoft.ACE.OLEDB.12.0" 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.ACE.OLEDB.12.0" for linked server "(null)".
I am running SQL Server 2008 r2 64-bit on Windows Server 2008 64-bit. I have installed Office 2010 and AccessDatabaseEngine_X64.exe available from
http://www.microsoft.com/downloads/details.aspx?familyid=C06B8369-60DD-4B64-A44B-84B371EDE16D&displaylang=en
I have tried reinstalling the ACE drivers and restarting the server. I am now slowly losing the will to live..
Please can someone help me? Any suggestions welcome..
Cheers,
Tom
PS I have looked at and attempted the answer here:

Changing Excel 14.0 to Excel 12.0, so that my query was:
SELECT * FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0','Excel 12.0;Database=E:\Project Data\339_IMP\Code_labels_latest_Sep09_breakdown.xls', 'SELECT * FROM [loftins$]')
changed the error to this:
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "(null)" reported an error. Access denied.
Msg 7350, Level 16, State 2, Line 1
Cannot get the column information from OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "(null)".
And corrupted my XLS (and XLSX) file(s).

Hi Greg,
Thanks for the response.
I ran:
SELECT * FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0','Excel 12.0;Database=E:\Project Data\339_IMP\Code_labels_latest_Sep09_breakdown.xls;HDR=YES;IMEX=1', 'SELECT * FROM [loftins$]')
And I got:
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "Microsoft.ACE.OLEDB.12.0" for linked server "(null)" reported an error. Access denied.
Msg 7350, Level 16, State 2, Line 1
