Installation problem, Pentaho won't run

I downloaded pdi-cd-5.0.1.A-stable.zip and ran the spoon.bat file. It unzipped but does nothing more.

When I run spoon.bat from the command prompt I get the following:

C:\Users\JeffDT\Pentaho\DATA-I~1>spoon

I'm running Windows 7 32 bit. Any thoughts appreciated.
