FernFlowerTask requires a 64bit JVM to run due to the memory requirements

Can you guess? You have to install 64-bit java, not 32-bit.

I have win7 32 bit.

You need a 64bit machine to genSources sadly, you can still make mods but wont be able to get the full features when looking at MC source in your IDE.

Just skip this step.
