I bought a new Dell laptop and paid money for 15th months McAfee subscription. But I am not able to activate it!|||You need to contact Dell then. Your serial key for McAfee is obviously invalid. They should supply you with a new one.
Phoning them will be the best solution if you want it fixed ASAP. Otherwise send their customer support centre an email and they should have it fixed. Possibly include screenshots showing the problem if you choose this option.|||Call Dell and explain the situation. Better yet, have them refund the amount of the software purchase and download Avast Free instead. McAfee is a joke anyway. Not nearly worth what you have to pay for it.|||It probably has a fee, download a decent free anti virus like AVG.
