Can 32-bit and 64-bit Java be simultaneously installed on Vista x64?

A:
Yes, and in fact, this is the only way to get Java Webstart, as there is no 64-bit version.
Edit: Supposedly a 64-bit Java WebStart will be available in Java 6u12.

A:
Considering that when you update Java, it never removes the old version of Java, you should be able to run 32 and 64 bit java at the same time without a problem.
