Your third-party antivirus (AV) software is still installed even after deploying the OSCE agent via Group Policy Object (GPO). All other installation methods are working successfully.
Automatic uninstallation of third-party AV software through GPO deployment is supported when the deployment method used is "Published" and it requires users to take action. Refer to the following KB article for more information: Deploying the OfficeScan (OSCE) client using Group Policy Object (GPO).
However, uninstalling third-party AV fails if "Computer Configuration" and "Assigned" are selected even before the user successfully logs into the system; the MSI package is already installing in the background. Because of this, the OSCE agent MSI installation process fails to uninstall the third-party AV because it checks specific UIs that are not present since the user is still logged into the system.
As a workaround, you can use different installation methods using Trend Micro Vulnerability Scanner (TMVS), Software Deployment (i.e. SCCM) software, login script, etc.
