Too Few Licenses

My district applied for sufficient licenses (we thought) for the computers in our district. Re-purposing older computers from the High school to the Elementary School and a grant have allowed us to add about 110 new clients to the network. I was not the Admin that obtained the licenses in the first place, but I am the one tasked with roll-out and the operation of AES. What do I/can I do about the shortage of licenses?
PS I know I’ve been asking a lot of questions this week and appreciate the patience and help I’ve been shown.

If you send an email to edu-support@avast.com then we can regenrate a license to cover your environment.
