dc9,
It works perfectly on my Windows 7 64-bit laptop. You need to make sure that you are using the 32-bit version of Internet Explorer.
In Windows 7 click Start > All Programs, you should then see two Internet Explorer shortcuts, one for the 32-bit version which is just 'Internet Explorer' and the other for the x64 version which is 'Internet Explorer (64-bit)'.
Make sure you use the 'Internet Explorer' shortcut. On a clean install of Windows 7 x64 the 32-bit version of IE is still set as the default browser.
To be sure you are using the 32-bit version, open Internet Explorer using the method above. Hold down the Alt key, then click Help > About. Make sure it DOES NOT say '64-bit Edition' next to the version number.
Good luck.
EDIT: dc9, sorry, I see from an earlier post that you have already tried this. Make sure its not the 64-bit Edition that is being launched by checking the about box.
