The following error message appears when trying to install the Plug-in Manager:

Installation Cannot Proceed
The wizard was interrupted before Trend Micro Plug-in Manager could be completely installed.
Your system has not been modified. To complete installation at another time, please run setup again.

The PLM_upgrade.log contains the following entries:

Property(C): POPUP_MSG_IDF_EXISTED = Unable to uninstall Plug-in Manager because Intrusion Defense Firewall is still installed. Uninstall Intrusion Defense Firewall from the Add/Remove Programs screen and then try uninstalling Plug-in Manager again.

The installation error shows when Plug-in Manager registry entries, folders, or files remain after a previous failed installation attempt, or when the files become corrupted.

To resolve this issue, remove the Plug-in Manager remnants:

  1. Delete the following registry entries:
    • HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\OfficeScan\service\AoS
    • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{5DB0ECA1-4C56-488B-9BF1-FB300D9E1F54}
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\1ACE0BD565C4B884B91FBF03D0E9F145\InstallProperties
    • HKEY_CLASSES_ROOT\Installer\Features\1ACE0BD565C4B884B91FBF03D0E9F145
    • HKEY_CLASSES_ROOT\Installer\Products\1ACE0BD565C4B884B91FBF03D0E9F145
  2. Delete the following folders:
    • ..\PCCSRV\PLM
    • ..\PCCSRV\Web\Service\PLM
  3. Delete the following files:
    • ..\PCCSRV\AosSrvUninstaller.exe
    • ..\PCCSRV\Pccnt\
    • ..\PCCSRV\Pccnt\Common\AosUImanager.exe
    • ..\PCCSRV\Pccnt\Common\CNTAoSMgr.exe
    • ..\PCCSRV\Pccnt\Common\CNTAoSUnInstaller.exe
    • ..\PCCSRV\Web_OSCE\Web_console\HTML\Addon\aos_promotion.htm
    • ..\PCCSRV\Web_OSCE\Web_console\HTML\Addon\aos_redirect.htm
  4. Run the Plug-in Manager installer.
  5. Restart the OSCE Master Service and the Plug-in Manager service via the Windows Services console (services.msc).
  6. Verify that the Plug-in Manager Service is installed.
  7. Check if the Plug-in Manager dashboard can be accessed without any errors.

If the Plug-in Manager Service is installed and the dashboard can be opened without errors, then the procedure is successful.

If the issue still persists, collect all CDT logs while reproducing the issue. Contact Trend Micro Technical Support to file a case.
