First Steps: Configure Control Pack

The first time that Control Pack is opened after the activation, you will be prompted with the "external requirements" window.
In case you don't have Nmap and/or Python already installed in your system, you can go ahead and click on "install"
It could also be the case that you have them installed but Control Pack cannot find them. Go to the Control Pack menu and choose "Edit preferences"
You will be presented with the above window.
Choose the paths for your interpreter, and Nmap. After you've done so, click on "check" and if they were configured correctly a window will pop up with the following message.
