Your path can include as many versions as you like however only the first version in your PATH will be the one chosen. This is how a PATH work. On all operating systems. This is how the class path also works.

I recommend using the x64 where ever possible on an x64 operating system because unless you have 32-bit DLLs, or running Java in a 32-bit browser, you are better off using the x64 version.
