serial number activate !!!

Hello my name is Murat;
I bought a new maximum security.
But I cannot activate the new serial number. When I look at my account, my internet security serial number is there. I can login to my account. But the new Maximum security activation does not work when I give an existing e-mail address. Can you help?

Hi @muratizci,

Thank you for bringing this up in our community.

Did you encountered any error message during activation? Kindly activate the subscription first on our Activation Portal and afterward you may download the suitable program for your chosen device.

You may also visit the page How to activate your Trend Micro subscription for more detailed guide on your activation journey.

Let us know again the result on your subscription activation.
