Error trying to create CSV file using Jet 4.0

I am successfully creating a CSV file using the Jet 4.0 driver on my development machine but the process fails on the customer's machine.

First I create a schema.ini file in the target folder as follows:

        [tmpExportFile.csv]
        Format=CSVDelimited

Then, I run the following command against a SQL Server database:

        INSERT INTO OPENROWSET('Microsoft.Jet.OleDB.4.0', 'Text;Database=C:\', [tmpExportFile#csv]) ( [col1], [col2] )  SELECT [mytable].[col1], [mytable].[col2] FROM [mytable]

On my development machine it executes correctly.  However, on the customer's machine the following error occurs:

        OLE DB provider 'Microsoft.Jet.OleDB.4.0' does not contain table 'tmpExportFile#csv'.  The table either does not exist or the current user does not have permissions on that table.
        OLE DB error trace [Non-interface error:  OLE DB provider does not contain the table: ProviderName='Microsoft.Jet.OleDB.4.0', TableName='tmpExportFile#csv'].

Changing the output folder to "NewFolder" causes a different error

        INSERT INTO OPENROWSET('Microsoft.Jet.OleDB.4.0', 'Text;Database=C:\NewFolder', [tmpExportFile#csv]) ( [col1], [col2] )  SELECT [mytable].[col1], [mytable].[col2] FROM [mytable]

        db error: OLE DB provider 'Microsoft.Jet.OleDB.4.0' reported an error.  
        OLE DB error trace [OLE/DB Provider 'Microsoft.Jet.OleDB.4.0' IDBInitialize::Initialize returned 0x80004005:   ].
        [OLE/DB provider returned message: 'C:\NewFolder\' is not a valid path.  Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.]

In both cases the the folders do exist and there is no existing tmpExportFile.csv file.  

Any ideas ???

Thanks,
