Thanks, Friedrich. I also found the following in the IPServer's
run.bat:

if "%JAVA_HOME%"=="" goto no_javahome
if not exist "%JAVA_HOME%\bin\java.exe" goto no_javahome

I have to decide whether to provide a web link for installing the JRE,
or to just warn them to do it.

BTW, I'm about to send you a big message on my thoughts regarding the
IPServer installation.
