You see this error message while installing the Trend Micro Security program on your Windows computer:

Installation Incomplete, please use the Uninstall Tool

"Installation Incomplete. Please use the Uninstall Tool and then try installing the software again"

Why did this happen?

There are remnants of previous versions of the program that prevents the installer to proceed.

It is also paired with either of these error codes:
