There may be several reasons for a failure of license activation/deactivation. Here are some things to verify –
- You have entered the activation key correctly.
- You have a working internet connection on the computer you’re using.
- You have not previously used the same key on a different system, if so please deactivate on that machine before activating on your current system.
- If you have made some computer hardware changes recently, it may affect activation. In this case, please contact support(at)simcontrolx.com.
