I'm trying to use it on windows but I get the following error :

Exception in thread "main" java.lang.UnsupportedClassVersionError: strat/mining/stratum/proxy/Launcher : Unsupported major.minor version 51.0

Could not find the main class: strat.mining.stratum.proxy.Launcher. Program will exit.

How to fix this ?

I think you have a JVM in 1.6 version (try "java -version" to check the version). Try to install a newer version: http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html
