Keyboard Macro Keys...

Hi all,

I'm running Windows Vista Home Premium 64-bit Service Pack 2 and use a Logitech Internet 350 Keyboard which has some macro keys above the function keys for opening Windows Media Player, Calculator, etc...

One of these keys is for the Internet Browser (I'm using Internet Explorer 9) and I'd like to know if there is a way to open the 64-bit version by default rather than the 32-bit version.

Thanks in advance.
