Automatic Updates Not Working in the Latest Version of Trend Micro Security for Windows

You might see this message on your computer with Trend Micro Security installed:

Unable to Connect to Trend Micro
Please check that you are connected to the Internet,
then click Update Now to get the latest protection.

Why did this happen?

This issue happens because the automatic update feature is not working properly in the current version of the program.

The program can’t get the latest security updates from Trend Micro’s servers as it should.

To make sure your protection stays up to date, the program shows this message to remind you to update it manually.
