FAQ

PsychLab is asking for a license code
Purchasing a license is required to activate and run PsychLab. Each License code will only work on one device. If you need to use PsychLab on a second device you will need to obtain a second license.

Please visit the Purchase page to obtain your single device annual license.

PsychLab is saying "License code is Invalid"

There are several reasons why you might receive this error.
1. Each license code will only work for a single device. If you try to use it on another device, it will not work, and you will need to obtain a second license code for the second device.
2. License codes are currently only valid for the latest version of PsychLab. Try an update to the latest version.
3. You may have input your code incorrectly. Try to copy/paste your code from the email sent to you rather than directly typing in the code, and if typing ensure you are using the correct numbers / letters (e.g. a zero may look like the letter "O")
