Release seats when formatting laptop?

I’m getting ready to format my laptop. Do I need to release my licenses for DTPro, Agent, and Sphere via the website, then add the same laptop back once finished?

These apps use a slightly different mechanism so you don’t need to remove seats for them.

So after I format my computer, DevonThink will recognize it as the same device for all three programs?

You should be able to activate the license for each app in your DEVONtech account online.
