I see there's portable java here, but does it include 64bit Java? I already got Java installed in my system, but there's this program i need to run that requires 64bit Java to run, for some weird reason. In order not to cause conflicts i dont want to install 64 version as well so i thought i should try some porable version...

what exactly do you need that for and what are you trying to do?
There is no reason why you could not have 32 and 64 java at the same time, as they will be installed into completely separate folders. There is no conflict at all, it is just normal installation if you use x64 IE.
I could so far not find any other use for it. But sure on my w7 x64 both versions are installed.

3D Subtitler asks for 64 bit Java. Anyway, would you say that i could use this portable version found here, or will it not do?
the java installer itself downloads the java in 32bit version and places it to the correct folder on the stick, so libre office or open office can use it or jar can be run with it using jportable launcher.
In fact, one can also simply copy/paste the contents of the java folder and all is done. The installer here is more for convenience so users do not need to search for java folder on the PC and do not need to install it if using non admin access.
But you could download the 64bit version from oracle, and just copy the content of the java\jre6 folder to the PortableApps\Commonfiles\java folder on the stick, the file names are all identical so it may work well if your program finds it.
I don't know how the program is going to use java. If it is a separate .jar then it can be started with the jportable launcher. If it is just some windows executable, needing java for some part of its work, then the program would need to be pointed to the right place to look for java first. Often this will do it by using generic windows mechanisms like registry entries, thus searching for java in the common place under program files\java\jre.
So the whole question is rather how and where is the program looking for java rather if java can be used portably. If you have means to tell the program where to look for java, you can place it where ever you want.
