How to Open IE 64bit using Browsers.Item(btIExplorer).Run();

Browsers.Item(btIExplorer, "",Browsers.pX64).Run();

See, Launching Browsers for details.

I'm not really sure why you would want to though... 99% of all browsers in the world are 32 bits. Firefox no longer has a 64 bits version, Chrome never had one, and IE 64 bits is mostly a novelty. Just to get Flash working you need to download a beta version well hidden on Adobe's site...



Besides, the only benefit from 64-bits architecture is to be able to use more than 3.5GB RAM. Personnally I never loaded a page so big as to need this.
