To resolve the issue:

1. Remove the current PHP using the Add/Remove programs under Control Panel.
2. Run the OSCE 11.0 setup program.
3. You may verify the PHP status using one of the following procedures.
    

   The instructions below assume that PHP was installed by OSCE, which uses the default path: C:\Program Files (x86)\PHP\.

   For IIS

   1. Ensure that the Module mapping values for PHP are as follow:

      Request path: *.php
      Module: FastCGImodule
      Executable: C:\Program Files (x86)\PHP\php-cgi.exe
      Name: FastCGI

      For more information regarding this executable path, refer to Step 14 of this Microsoft article Install and Configure PHP.
   2. Check the following registry key:

      [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\PHP]
      "InstallDir"="C:\\Program Files (x86)\PHP\"
      "WebServerType"="iis4FastCGI"
      "Version"="5.3.27"

   3. Make sure that the PHP extensions below exist under C:\Program Files (x86)\PHP\ext:

      php_com_dotnet.dll
      php_curl.dll
      php_gmp.dll
      php_ldap.dll
      php_mbstring.dll
      php_openssl.dll
      php_pdo_sqlite.dll
      php_soap.dll

   For Apache

   1. Ensure that these two (2) configures are on httpd.conf configuration file to load the PHP module for Apache 2.x:

      #
      LoadModule php5_module " C:/Program Files (x86)/PHP/php5apache2_2.dll"
      # configure the path to php.ini
      PHPIniDir "C:/Program Files (x86)/PHP/"

      For more details, refer to the article Apache 2.x on Microsoft Windows.
   2. Check the following registry key:

      [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\PHP]
      "InstallDir"="C:\\Program Files (x86)\PHP\"
      "ApacheDir"="C:\\Program Files (x86)\Trend Micro\OfficeScan\PCCSRV\Apache2\conf\"
      "Version"="5.3.27"
      "WebServerType"="apache22"

   3. Make sure that the PHP extensions below exist under C:\Program Files (x86)\PHP\ext:

      php_com_dotnet.dll
      php_curl.dll
      php_gmp.dll
      php_ldap.dll
      php_pdo_sqlite.dll
