I have multiple platforms that I use for work. Sometimes I am on a Windows machine, sometimes on Linux, and sometimes on a Mac. What I would like to do is to buy one license of the software and install it on multiple machines so that I can use it on whichever machine I am currently using. I would not be using the software on two platforms simultaneously, only one at a time, on whichever I am currently working on.
What is the licensing policy for this type of work environment? Which license(s) are valid for this type of environment?
