Hello,
Deploying a .exe installer like the Trend Micro Agent through Group Policy is not straightforward because GPO natively supports MSI packages for software installation under Computer Configuration → Policies → Software Settings → Software Installation. An .exe cannot be directly pushed in the same way. If you attempt to assign or publish an .exe via GPO, it will fail because Windows Installer service expects MSI metadata.
The correct approach is either to obtain the MSI version of the Trend Micro Agent from the vendor (Trend Micro usually provides MSI packages for enterprise deployment) or to wrap the .exe into an MSI using a repackaging tool such as Advanced Installer, WiX, or Microsoft’s Orca. Once you have an MSI, you can place it in a shared folder with read permissions for Domain Computers and then configure the GPO to install it at startup.
If you must deploy the .exe directly, the supported method is to use a GPO startup script. Place the .exe and its supporting folder on a network share, then configure a startup script under Computer Configuration → Windows Settings → Scripts (Startup/Shutdown). The script should call the installer silently with the appropriate command-line switches, for example:
Code
\\server\share\TrendMicroAgent\setup.exe /silent /norestart
Make sure the installer supports silent installation parameters; Trend Micro documentation specifies which switches are valid. The script runs under SYSTEM context, so the share must allow access for machine accounts.
I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!
