I downloaded jython-installer-2.7-b3.jar and attempted to install. I specified the "standalone" option.

Unfortunately, the install fails as follows:
$ Exception in thread "Thread-6" org.python.util.install.InstallerException: Error accessing jar file

If I did the same thing using 2.7-b2, no problems were encountered.
