Clipstudio, reusing the same key/use in another desktop

[Lii]

Hi

Every clipstudio key can be used in two different pc, but I have alredy use one time on my pc, but I wanted to reinstall clipstudio after I reinstall windows on my pc (same hardware/w10key), but Im not really sure if it will count as a second utilize or as the first one

if it will count as a second utilize, there is not any way to remove the "first use" before I reinstall windows, and use that "first use" after I reinstall windows?

going around clipstudio application, I didnt notice any similar/contex settings,

I have already quested on clipstudio forum, but all replies were in japanese, and the traslation from google were pretty crap, so I couldnt really understand.. so anyone know anything about?
