OPTION 3: Reinstall/ Upgrade to the latest version of Trend Micro Security

Uninstall your Trend Micro Security using the Trend Micro Diagnostic Toolkit, then reinstall the program. Do the following:


On April 8th, 2014, Microsoft formally announced the Windows XP end of support. Because Microsoft no longer fixes issues on Windows XP, it has become increasingly difficult for Trend Micro to keep users safe on this operating system. We encourage all of our users to upgrade their PCs to a more modern operating system which will provide greater stability and security. You can refer to this article for more information.
  1. Go to Start > All Programs > Trend Micro (program version) Security > More Tools & Help >Trend Micro Diagnostic Toolkit.
  2. Click (C) Uninstall tab.
  3. Click 1. Uninstall Software, then wait while the program is being uninstalled.
  4. Click Yes when prompted to restart your computer.
  5. Download the installer file to begin the installation.
    Serial Number Starts with an 'X'
    Maximum Security
    Serial Number Starts with a 'P'
    Internet Security
    Serial Number Starts with an 'A'
    Antivirus+ Security


    If your serial number starts with "T", contact Best Buy or your Internet Service Provider, depending on where you got the product.
  6. Double-click the installer to run it.
    Click Yes when the User Account Control window appears.
  7. Wait for the installer to extract the files needed for the installation.
  8. Wait as Trend Micro checks if your computer is compatible for installation.
    System Check
  9. Type your serial number, then click Next.
    Type serial number


    If you forgot your Trend Micro Serial Number, check this Knowledge Base article:

  11. Wait for the program to install. This may take a couple of minutes.
