"Installation Stopped. Switch to a computer with a supported operating system"
This article explains why the error appears and walks you through what to do next.
Why Did This Happen?
Trend Micro checks your operating system before installation begins. This error means your current version of Windows doesn't meet the minimum system requirements for Trend Micro Security.

- Press the Windows key + R on your keyboard.
- Type

- Compare it against the Trend Micro system requirements.
Option 2: Upgrade Your Windows Version

- Go to Settings > Update & Security > Windows Update (or Settings > Windows Update on Windows 11).
