Issue:
How many times am I able to install the one license I have purchased?
Solution:
You can install using a single-user license and serial number up to five times on no more than three computers, as long as it is intended for a single user. This is not intended to allow multiple users on different computers, or at the same time.
If you replace an old computer and you will go over the installs, just let us know (orders@fontlab.com) and we'll allow additional installs.
