Cannot install helper tool error from Trend Micro Antivirus for Mac

You may get this message after installing Trend Micro Antivirus on your Mac:

"Cannot install helper tool. The helper tool is needed to open Trend Micro Antivirus."

Why did this happen?

Without the Privileged Helper Tool, Antivirus for Mac cannot launch and do scans to protect your computer from threats.

How do I fix this?

1. Restart your Mac.
2. Open Trend Micro Antivirus.
3. Enter your Mac password, and then click the Install Helper button.

   

   You should now see the Trend Micro Antivirus main app window.

It says "Something went wrong"

1. Click OK.
2. Enter your password.

   If you already clicked OK, but there is no pop up notification to type your password:

   1. Restart your Mac.
   2. Open Trend Micro Antivirus.
   3. Wait for the Install Helper Tool pop up to show again.

If the pop up does not show even after restart, give us a call or start a chat and let our Trend Micro Support Representatives help you.
