        Process test = new Process();
        test.StartInfo.FileName = "java.exe";
        test.StartInfo.Arguments = launch;
        test.Start();

All the time im getting "unable to access jarfile net.minecraft.client.main.Main

Answer 1

You are not specifying the jar file to run in your arguments:

"-jar " + "-Djava.library.path="

The first argument after -jar must be the path to the jar you are running.
