Renew for 2 pc's

[Labdoc]

I have a current licence for Reference dBPA and Perfect Tunes on my desktop pc. I need to renew to continue receiving updates in 2 days. I want to install to my desktop and my portable. What do I need to buy to do so: Family Pack or does a single user licence allow 2 pcs for the same user?

Family pack is needed for concurrent installs.
