Excel connections in SSIS 64-bit

This is a new one on me…when running SSIS in a 64-bit environment, Excel connections (and Access as well I presume) do not work, as the OLE DB Provider for Jet is not supported.

At a current client, they are moving the server platform from Windows 2003 Server to Windows 2008 Server 64-bit.  I had developed some ETL packages for them, pulling data from Excel and CSV sources.  The packages get executed when the files have been unzipped and downloaded to a specified folder.  This is done via simple batch files, which are along the lines of the following:

dtexec /f "F:SSIS PackagesReportingImportClientCSV.dtsx"

When I moved all the packages to Windows 2008, the CSV packages ran no problem.  But when I tried to execute one that imported from Excel, I received the following error:

Code: 0xC00F9304
   Source: ImportClientXLS Connection manager "Excel Connection Manager"

   Description: SSIS Error Code DTS_E_OLEDB_EXCEL_NOT_SUPPORTED: The Excel Connection Manager is not supported in the 64-bit version of SSIS, as no OLE DB provider is available.

In order to use the OLE DB for Jet providers, the packages must be run in 32-bit mode.  This is done by using the x86 version of dtexec and specifying the "/X86" switch.  I amended the batch file in question to look similar to this:

"C:Program Files (x86)Microsoft SQL Server100DTSBinndtexec.exe" /f "F:SSIS PackagesReportingImportClientXLS.dtsx" /X86

Voila!  The package ran successfully.
