Why am I getting this message?

Your Trend Micro programs have different license seats:
  • Maximum Security = 3 seats
  • Internet Security = 3 seats
  • Antivirus+ Security = 1 seat
The error mesage appears when there are no available license seat left for your program. The license seat is used when you:
  • Install the program on your computer or other computers
  • Install the program on the same computer more than once
  • Reinstall the program on the same computer after reformatting its hard drive
  • Upgrade the program on the same computer where an old version was previously installed


What can I do to resolve this issue?

To resolve this issue, transfer the protection from a previously made activation on your account to the computer where you are installing the program. Here are the steps:
Note: You can also watch an audio-video guide for instructions.
  1. Type your password in the Password field, then click Next.

  3. Click Next.
    A confirmation window will appear.
  4. Click Finish.
    You have now activated the protection on the computer.
