Having had problems with the ZeroG free version installer for CTCjava on Win XP and current Java releases, here are instructions for how to work around any failures on that platform.
If the installer fails to run (I've had this happen under WinXP Home,
where even a copy of the installed system executable will not run, but not
WinXP Pro), then you have to fall back to a variant of the Linux strategy
below. Download the Linux cj_setup.zip archive
and the CTClib 2.3.1 patch dll archive. Extract the .jar file from the
former, and the dll from the latter, and put them in the same folder. Now
create a ctcjava.bat file that has commands to change to the partition and
then cd to the folder where you have placed these files, and then executes
wjview /cp:p ctcjava.jar com.ravnaandtines.ctcjava.CTC
ctcjava.ini
to use the Microsoft VM, which is what I needed to use to get it working at
all, or
javaw -cp ctcjava.jar com.ravnaandtines.ctcjava.CTC
ctcjava.ini
(with the javaw for the JDK or equivalent jrew command for the JRE preceeded
by the path to the Java installation's \bin folder if it's not on the path)
to use a Sun JRE if that works for you.
Put a shortcut to this on your desktop with an icon as desired.
