WINDOWS 7 and above

1) download SKCraft launcher v4.3.3 and put it in a dedicated folder inside your document folder

2) launch it and close it. It should have created a subfolder called "instances" :
\<SKCraft Launcher home dir>\instances

3) select any package and unzip it in the instance folder as is, final structure should be like :
\<SKCraft Launcher home dir>\instances\<Alice 1.x>\minecraft\ ...

4) launch again the SKCraft launcher, it should detect and list immediatly the unzipped package
