This is improved based on mathematica keygen.
You can use your own key to activate,and it has full tutorial inside
It also includes systemmodeler keygen.
It's available for any version of mathematica and system modeler.
I will include the magic numbers here.
for mathematica: { 36412 24816 44011 33360 35944 59222 },
for system modeler : { 48967 4912 62774 42446 30046 4961 61182 31889 22384 },
Hope everyone enjoys it!
