Where or how do i find out who i have got sharing my Licence number

I had purchased a 4 computer licence AVG internet security,how do i find out who i have nominated to share it with ?

Hi Eileen, Sorry for the inconvenience, you can't find on which computers you have shared the license number with. If you want you  can open each computer and open the AVG internet security program, then click on the Support button on the top right corner. It will display the license number used in that computer. Thank you
