FG Lisence?

Brought an extra computer for a game to run for friends I haven't seen in 16 years. I don't remember where to look up my ultimate lisence.

You cant install your license on multiple computers.
Just have them install a demo license and they can connect to your Ultimate installation.

If you bought via the store go to the store page and then click the store drop down at the top right. Select purchase History and then click on the date of the license purchase to see your key. If you bought via Steam look at the right hand menu on Steam and select CD Key to see your license key. I am assuming this is what you were asking.
