If you are unable to activate your serial number, please refer to the following possible reasons and corresponding solutions.


1. Incorrect software used


Please confirm that you have downloaded the correct version of XMind software. The serial number of Xmind 8 Pro can only be used to activate Xmind 8 and cannot be used to activate other non Xmind 8 software, such as Xmind 7 or Xmind desktop version.

2. No complete serial number entered


The serial number of Xmind Pro is composed of 5 lines of letters and numbers. When activating the serial number, you need to copy and paste the complete row serial number into the serial number verification box.


3. Exceeding the number of authorized devices


A Xmind Pro serial number can only be used for two devices of the same user. If one of your serial numbers is used on more than two devices, you will need to purchase an additional serial number to use it.
