Fix "The App You Are Trying to Install Isn't a Microsoft Verified App" Message When Installing Trend Micro

When trying to install Trend Micro on your Windows Computer, old or new, you encountered this message:

Why did this happen?

Since Windows 10 build 15042, Microsoft has introduced a new setting that restricts app installations to those from the Windows Store exclusively. This also happens when your computer is in S mode.

How do I fix this?

Turn off App Recommendations

1. Click the Start >Settings >Apps> Apps & Features.
2. Below "Choose where to get apps", click and change the options from "The Microsoft Store Only(Recommended)" to "Anywhere" (Options vary by Windows version.)
3. Close the Settings and try to re-install Trend Micro.
