Communicating Arduino 1.0.5 with Processing 2.0.1 64-bit

I have tried to follow the instructions to the letter but all I get is this error message:

serial does not run in 64-bit mode.
processing.app.SketchException: serial is only compatible with the 32-bit download of Processing.
at processing.mode.java.runner.Runner.(Runner.java:108)
at processing.mode.java.JavaMode.handleRun(JavaMode.java:116)
at processing.mode.java.JavaEditor$19.run(JavaEditor.java:472)
at java.lang.Thread.run(Thread.java:662)

I would think that 64 bit should not be a problem.
