How to fix this error quickly?

This application Requires a Java Runtime Environment 1.6.0
In my case it worked to download & install java 1.6.x from http://www.oldapps.com/java.php?old_java=36
an alternative download locations might be:
http://www.filehippo.com/download_jre_32/6490/
http://www.filehorse.com/download-java-runtime-32/9827/

or DL newest (heavy weight version) at http://java.com/en/download/
