When activating iolo products, please make sure that you are using the correct product that they Activation Key is meant for and that you are typing the characters correctly, such as 0 (zero) versus O (oh) and the letter I (eye) versus l (L). It is best to use all upper-case so that there is no confusion. 


Most common causes of activation keys not being accepted:

  • Typing the activation key incorrectly.

  • Copying and pasting the key into the product which can also copy blank spaces.

  • If you have an earlier version of System Mechanic, such as System Mechanic 15, and are trying to activate with an Activation Key meant for System Mechanic 16 or greater, the key will not work.

  • If you have installed System Mechanic Ultimate Defense (or Phoenix 360) and are attempting to use a System Mechanic or System Mechanic Professional key, the key will not work.

  • However, if you have previously purchased Phoenix 360, your Phoenix 360 Activation Key will allow you to upgrade to System Mechanic Ultimate Defense. Phoenix 360 has been re-introduced within the System Mechanic product interface as System Mechanic Ultimate Defense. Your product will automatically upgrade to System Mechanic Ultimate Defense when you update Phoenix 360 to the latest version. Your key will remain the same, with any service time retained.

  • If you have purchased multiple Activation Keys for the same product, the key you are attempting to use may be one that has already expired.

  • If you have purchased two different versions of System Mechanic, such as System Mechanic and System Mechanic Professional, you may be using a key meant for the opposite version.

  • If you had sought a refund for a product, the key will not work.

  • If your product has expired, your Activation Key will not work until you add time to your subscription.

  • There may be a legitimate issue with the key itself and you should contact Customer Care to assist in quickly resolving it.
