Bob,

As you must have suspected, my machines did not have the Java software
installed. I installed Java 1.4.0. When I type "java -version" I get:

__________________
D:\>java -version
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)
_______________________

Having done this, I re-ran the install and it seemed to complete correctly.

When I clicked on the DecoderPro icon on the desktop, it blinks, but nothing
seems to happen.

If I execute "decoder pro" from within a command prompt defaulted to the
d:\program files\jmri folder, I get the user interface which looks
reasonable. I am not connected to my railroad now. The program interface
seems to work o.k. When I quit, the command prompt window contains:
