I recieved Presonus Studio One and can not find my serial number for EZ Drummer Lite or Guitar Rig LE.

The easiest way to find your serial number is to click Help inside of Studio One, navigate down to Studio One Installation. In that page you will find all of your associated serial numbers and it will show you the components you have installed and where they are installed. The EZ Drummer and Guitar Rig codes are there.
