To resolve the issue, manually reinstall Application Control. Follow the steps below:

1. Copy the Application Control server file in the Apex One folder.
   If the Apex One server doesn't have files, copy files into the Apex One folder (e.g. copy {Apex One Server Installation folder}\PCCSRV\Admin\Utility\iServicePackage\iAC folder files to {Apex One Server Installation folder}\iServiceSrv\iAC).
2. Create an IIS web site.
   1. Open a command prompt with administrative privileges.
   2. Navigate to [installation path]\Trend Micro\Apex One\iServiceSrv.
      Example: cd C:\Program Files (x86)\Trend Micro\Apex One\iServiceSrv\iAC
   3. Run the following command:
      TMiACSetup.exe "-installation" "-setup_iis_setting" 1
       

      Note the following values:

      • 0 means Apex One server is installed in IIS virtual web site
      • 1 means Apex One server is installed in IIS default web site

       
3. Set Application Control server configuration (SSL port default: 4343). Run the following command:
   TMiACSetup.exe "-installation" "-save_osf_web_info" 1 {ApexOneServerHostname} {ApexOneServerWebServerPort} "/officescan/osfwebapp/api/v1/SystemCall"
4. Install the Application Control server service. Use the command below:
   TMiACSetup.exe "-installation" "-install_product_service"
5. Create a database table by running the command:
   TMiACSetup.exe "-installation" "-initialize_database" {sql_instance} {sql_db_name} {sql_login_user} {sql_login_password} {sql_win_authentication}
    

   As an example:
   TMiACSetup.exe "-installation" "-initialize_database" {SQLDB}\{OFFICESCAN SQLDB-ApexOne} sa P@ssw0rd 0
   
   Where:

   • sql_win_authentication=0, will not use Windows Account
   • sql_win_authentication=1, will use Windows Account

    
6. Copy the Application Control agent install package to Apex One. Use the following command: TMiACSetup.exe "-installation" "-copy_agent_package"

After completing the manual installation of Application Control, follow the steps below to verify that the installation was successful:

• The service for application control is now visible on the Services console:

  

• The OfficeScan_iAC_AppPool is now available in IIS Manager:
