How to install License Key for SAPNW2004sJavaSP9_Trial

My SAPNW2004sJavaSP9_Trial License got expired, So I have applied for the License key from LAS and I got the License with me.

I have no idea of how to proceed with this further.

Can you experts help me with this.

Also is there a way to get the permanant license.

Thanks,

Senthil
