Solution :

Make sure you are typing the product key correctly. You can confirm this by visiting  www.quickheal.com/builds.asp  from your PC and entering your product key. If the key is not getting accepted then it means you have typed the key incorrectly. If the key is getting accepted then it means you are trying to activate the wrong Quick Heal mobile security pack on your mobile with the product key in hand.

Cause :

This problem could arise if you have downloaded the wrong Quick Heal mobile security pack especially from some third party website like android market, mobile9.com etc. As you see there are 2 types of Quick Heal mobile security packs available, Lifetime Pack and Freedom Pack. The product you have downloaded and installed could be Lifetime pack but the product key you are using to activate could be of Freedom pack or vice versa.

Hence you need to download and install the exact product based on the key you have purchased.

You can download the appropriate product pack by visiting www.quickheal.com/qhms from your mobile phone or visiting www.quickheal.com/builds.asp  from your PC and entering your product key.
