No, they won’t work.
This post has some shell scripts you can use to launch a client on a 32-bit system using a JRE that’s already installed. They require the JAVA_HOME environment variable to be set.
We’re shipping slightly more polished versions of these shell scripts with 8.0.2 or 8.0.3, but that’s the extent of support/workaround we’re going to have for 32-bit systems.
