Can I install the software on multiple machines?

As explained in our terms and conditions, "you are granted a personal license to use the Product on one or several machines, as long as you remain the sole user of the Product".

So if you do not share the computers with others, you can install the software on as many machines as you want. You do not need to purchase extra licenses, unless you are sharing the computers and installed software with other people.

No extra step is required to authorize multiple machines.
