Check serial number

I have Trend Micro Antivirus+2016 running on 3 computers with 560 days left. Unfortunately my main computer has given trouble and now I'm getting messages saying my time has run out for the Antivirus. I've tried using the serial number from one of the other computers without success. I've also installed the trial version and the same serial number again without success.

What can I now do? I'd be very grateful for any advice.

Hello Claudia.  Thank you for your reply.

My exact registration data is as follows.

Trend Micro Antivirus+ 2016
Serial number ***removed private information***
559 more days left.

Having lost the software when my computer broke down somewhat I installed the Trial edition and tried to enter the above serial number.

The exact error message I get is "You have not provided a valid serial number."

Thank you

Hi Anthony,

Please make sure that you download the correct installer which will work with your serial number. And based on the serial number you provided, you should be installing Trend Micro Antivirus+.
