(I have too low reputation to comment, but this is comment on JoshCaba's entry, using the Ace-engine instead of Jet for Excel 2007)

If you don't have Ace installed/registered on your machine, you can get it at: https://www.microsoft.com/en-US/download/details.aspx?id=13255

It applies for Excel 2010 as well.
