Javaws 64-bit fails to installer newer JRE  (Java7u6 auto-upgrading to u7)

892235 Newbie
Currently Being Moderated

I have a machine with an previous version of java installed (tried with 1.7.0_06).

My Jnlp file is set to automatically download the latest JRE. This works fine if the JRE installed is 32-bit. But if the user has downloaded the x64 bit version (on windows 7), everything works, except when I change the required version spec to 1.7.0_07.

The confirmation dialog to install 1.7.0_07 comes up but fails, as it tries to download and run the 32-bit installer while the javaws is 64-bit. Shouldn't the 64-bit version download a 64-bit version when auto-downloading?

The user is running javaws from the commandline
javaws.exe http://myserver/myapp.jnlp

h3. This is the jnlp file generated by javaws to auto download the JRE
<jnlp codebase="">
<title>J2RE 1.7.0_07 Installer</title>
