To resolve this:

1. Download and save the appropriate Windows Installer Package to a local folder in the OfficeScan server.
   • For OfficeScan 11.0: php-5.3.27-nts-win32-VC9-x86.msi
   • For OfficeScan 10.6: php-5.3.5-nts-Win32-VC9-x86.msi
2. Open a command prompt as Administrator.
3. Change the directory to the location where you saved the Windows Installer Package.
4. Run the command:
   • For OfficeScan 11.0:

     msiexec /i php-5.3.27-nts-Win32-VC9-x86.msi /q ADDLOCAL=iis4FastCGI,ext_php_gmp,ext_php_openssl,
     ext_php_pdo_sqlite,ext_php_ldap,ext_php_curl /L C:\PHPInstall.log

   • For OfficeScan 10.6:

     msiexec /i php-5.3.5-nts-Win32-VC9-x86.msi /q ADDLOCAL=iis4FastCGI,ext_php_gmp,ext_php_openssl,
     ext_php_pdo_sqlite,ext_php_ldap,ext_php_curl /L C:\PHPInstall.log

    

   The command should be run in one line.
5. Log on to the OfficeScan management console and verify if the summary screen is working.

If you continue to encounter errors indicating "Server Error in Application OfficeScan" or "HTTP Error 403.1 - Forbidden", do the following:

1. Go to the Summary screen and check the detailed error information. Verify that the file is having the error under Handler "PHP_via_FastCGI".
2. Open the Internet Information Services (IIS) console and navigate to the OfficeScan website.
3. Access the following path under the OfficeScan website and highlight it:

   OfficeScan > console > html > widget

4. With the Widget folder highlighted, double-click the Handler Mappings option under the IIS section.
5. Locate and select the PHP_via_FastCGI service. Right-click the service and then select Edit Feature Permissions. If you do not see the PHP_Via_FastCGI service, as shown in the screenshot below, do the steps that follow it:

   

   1. Under the Handler Mappings, select Add Module Mapping and enter the details as can be seen in the screenshot above.
   2. For the executable (optional), browse to the location of the php-cgi.exe on your OfficeScan server. It is usually stored in …\Program Files (X86)\Trend Micro\OfficeScan\PCCSRV\PLM\PHP\php-cgi.exe.

      

   3. Once this has been added, please proceed to step 6 and verify step 7.
6. Verify that the PHP_via_FastCGI service now appears under the Enabled section (indicating that its status is "Enabled").
7. Log on to the OfficeScan management console and verify if the Summary screen is now working.

If the issue persists, collect the IIS Logs and contact Trend Micro Technical Support or your Technical Account Manager (TAM).
