Canon Imageclass D320 All-in-One Printer not installing in Windows 7

I definitely do see 64-bit Windows 7 drivers for the D320 at http://www.usa.canon.com/cusa/support/consumer/printers_multifunction/imageclass_series/imageclass_d320#DriversAndSoftware  In addition to the operating systems you listed they also show Vista and Vista 64-bit and Windows 7 and Windows 7 64-bit. 

I am using Firefox as my Internet browser.  However if I  use exactly the same link using Internet Explorer 9 I don't see any Windows 7 drivers.  If I use Internet Explorer 9 and change it to Compatibility View I can see all of the drivers.  (To do that in IE 9 just click on  the little icon that looks like a page of paper torn in have -- in the address bar to the left of the refresh button -- or go to the Tools Menu and select Compatibility View)

This is the second time that I've seen this problem with the Canon driver website (where I was seeing one thing and the person I was trying to help was seeing another thing at the same link).

Here is a picture of what I see at the Canon site, with the Choose Operating System dropdown selecting the Windows 7 64-bit driver:
