Java update mess up ?

Serviio was fine, till I updated my Java (as requested to do my windows), no I get

No JVM could be found, on your system, please define EX4J_JAVA_HOME

Java says its up to date and OK. I have uninstalled and re-installed it but still the same ?

Windows 7 64 bit, Java 7 update 75

Any ideas ?

Many thanks.

Uninstalling Java, then installing 32 and 64 bit versions fixed it.
