Substance painter License

Hi ,

We are company.We use 3xSubstance painter.

Before we have one account with 3 license.

I download file the 3 licenses and sent to emplyer who use it.

Is there any licence file when i bought from Adobe page?

Can I bought 3 x substance painter from one account?

or I just need to bought 3 licensec from 3 account?

Do you use license files too or i need only to log in to adobe account?

I don't want to log for 3 account and download 3 license file.
