Hello, I have a current subscription of TM Titanium Internet Security that allows 3 PCs. Can I not renew my second PC TM security with one of the 2 remaining? After entering the serial #, it is not accepted. Thank you for info.

It should allow you to install the Trend Micro program on your other computers using the same serial number that you have used for the primary computer. The message that tells you that the serial number is invalid would come up if the installer that is being used is not the one intended for the serial number format. With that, please refer to the links below for the instructions in installing Titanium Internet Security depending on the format of the Serial Number you have:
For Serial Number format: Pxxx-xxxx-xxxx-xxxx-xxxx
For Serial Number format: Dxxx-xxxx-xxxx-xxxx-xxxx
For Serial Number format: Txxx-xxxx-xxxx-xxxx-xxxx
