Yes, you can install the Philips SpeechExec Pro v7 software on multiple computers, however; in order to use it on multiple computers, you will need to ‘Revoke’ the license on the computer that you won’t be using and ‘Activate’ the license on the other computer. 
With this licensing, you are not able to concurrently run the software on multiple machines, however; you can switch back and forth as needed.
If you need to concurrently run the software on multiple machines, I would recommend purchasing another license.
