X6 Print Merge

Print Merge,  X6,  win7-64,  Excel 2010 (and Excel 2002

Seems I can no longer access load data from .XLS file.  Still works (on same PC) on X5.  What's the deal on that?  Or better yet,  what is the solution.

File>Print Merge>Create/Load Merge fields...>Import Text from file or ODBC data source>ODBC Data Source>Select ODBC Data Source>Machine Data Source>Excel Files

The above menu path yields the following error:  "The specified DSN contains an architecture mismatch between the driver and the application."

I understand I can save as a tab delimited file and work past this, but it is so convenient to work direct from the .XLS file.
