Some activation issues in Malwarebytes Premium are caused by minor errors, such as an incorrect or missing character. Malwarebytes for Windows, Malwarebytes for Mac, and Malwarebytes for Android may not accept your license key if:
- the characters in your license key have been entered incorrectly.
- the license key is not compatible with the Malwarebytes product you are trying to activate.
- the license key is expired, blacklisted, or has been activated too many times.
To help resolve activation issues, we recommend you:
- check your license key for missing or incorrect characters. For example, the letter S can be mistaken for the number 5.
- copy and paste your license key instead of typing in the key manually.
- make sure you’ve entered your license ID, if you have an ID.
If you’ve tried activating your license key and received an error message, refer to the errors below for further assistance.
