The installer looks first for the JAVA_HOME environment variable
if it didnt find the variable it will then look in the registry under 
hkey local machine,
"SOFTWARE\JavaSoft\Java Runtime Environment\xxxxxx\JavaHome"
where xxxx is the value under the registry key "SOFTWARE\JavaSoft\Java 
Runtime Environment\CurrentVersion"

if it doesnt find that, it will show the error.


Can you verify that either JAVA_HOME enviroment variable or that there 
are the settings in the registry?
