I'm not sure if there is one. If you are trying to download 64-bit Java you could go to start menu and search "64" and 64 bit IE will come up.I think there is a 64-bit beta https://www.google.com/landing/chrome/beta/

I'm back from my eternal slumber of 2 or 3 months. A long-ass time.
Oh boy, visual basic. I can barely contain my excitement.Not.
Of course there is no tangible reason to use the 64-bit version. Browsers don't really do anything that could benefit from 64-bit instructions. Firefox could probably benefit from the larger address space, but it would probably just mean that it leaves more uncollected garbage for longer periods. Chrome can't really suffer from the limited address space as a 32-bit application because each tab is a separate process that has it's own usable 2GB Address space.
That isn't to say that no programs will benefit, but personally I think people are rushing into it too much. The fact is that we didn't get 32-bit Operating systems mainstream until 8 years after 32-bit processors were released; the fact that 64-bit adoption is progressing so quickly in relation to when the first ia64 processors were released is quite impressive, but this takes time.
Of course there were 32-bit applications before 32-bit operating systems; things like Autocad and other such programs would switch the processor to protected mode, as with many games. This was actually rather useful- only those programs that truly needed the capabilities of 32-bit ran 32-bit, because there was the overhead of learning how to do so. Now, it seems that a lot of the push for 64-bit is driven merely by people not liking that *32 on the end of their process names, which is a silly reason to want a 64-bit version.
Browsers don't really do anything that could benefit from 64-bit instructions. Firefox could probably benefit from the larger address space, but it would probably just mean that it leaves more uncollected garbage for longer periods.
Pretty much my exact thoughts.
There is really no point in running an x64 browser.
