Java web start fails to start - JRE 7 32 bit (running on 64 bit windows system)

Question

I have removed all JDKs/JREs (using the uninstaller), removed the JavaSoft stuff from the registry, removed JAVA_HOME from the environment variables, removed any reference to Java in the "Path" environment variable.

Then I installed JDK 7u11 for 32 bit system.

When I try to use Java webstart (either via the browser or directly from the command line), I get the Java 7 splash screen briefly, and then a dialog that says "Unable to Launch the Application", clicking on the "Details" button yields this:

java.lang.NullPointerException
    at com.sun.deploy.config.JREInfo.validateHomeJRE_int(Unknown Source)
    at com.sun.deploy.config.JREInfo.initialize(Unknown Source)
    at com.sun.deploy.config.ClientConfig.refreshProperties(Unknown Source)
    at com.sun.deploy.config.ClientConfig.init(Unknown Source)
    at com.sun.deploy.config.WebStartConfig.init(Unknown Source)
    at com.sun.deploy.config.ClientConfig.<init>(Unknown Source)
    at com.sun.deploy.config.WebStartConfig.<init>(Unknown Source)
    at com.sun.javaws.Main.main(Unknown Source)

I am executing the right javaws.exe file (I'm trying this with the command line to be sure).

I googled this and found only one unhelpful link:
