You'll need to open up NI License Manager and log into an NI.com account. If you do not have an account, a team member or mentor should create one for the team.
Once you are logged into an account, go to the "Local Licenses" tab of NI License Manager and find the software you need to activate. Unlicensed software will have a gray icon, expired licenses will have a red icon, and evaluation licenses will have a yellow icon.
Once you've identified the software to activate, right click on that item and select "Activate." When prompted for a Serial Number, enter the number from your Software Packet.
