Maybe you should Google it? I don't know, maybe Google can provide something in your language?
People these days...
You need to download a source from the Tutorials/Source Code section. Install a varying version of the Microsoft .NET Runtime Environment, depending on the source. Get the latest version, and substitute if needed. Get a C# compiler. Install a MySQL daemon, preferably XAMPP/WAMP.
If you need to, grab a Flash compiler for an AS3 source.
Compile the needed assemblies and then run them. Follow any setup necessary for a database.
Is that clear enough?
