Problem opening spreadsheet in Excel when using latest Google Chrome

We are using SP 2010 service pack 2.

We have the lists set to default to opening files in their native external application instead of opening within browser pages.

A user reports to me that when he attempts to open an Excel spreadsheet, he gets the error "To open this workbook, your computer must have a version of Microsoft Excel installed and your Web browser must support opening files directly from Excel in the browser."

He gives me the URL. Using IE, I go to the doc library, click on the spreadsheet, and it opens in Excel without a problem. He then tells me he is using Chrome. I don't have Chrome at that time, so I try to open the spreadsheet in Firefox. it works fine there. I install the latest Google Chrome. I go to the URL. I click on the file. It opens the file in the browser page instead of in Excel. There is a button on the page that says "Open in Excel". I press the button. I get the above error message.

I know that according to microsoft, Google chrome is supported.

Does anyone know what to do to fix this issue for chrome?

Thank you.
