The issue happens due to any of the following reasons:
- The error occurs by mapping an incorrect PHP-CGI.exe.
- The PHP-CGI.exe application is missing from the %Program Files%\PHP folder.

To resolve the issue:
- Open the Internet Information Services (IIS) Manager.
- Navigate to <Server_Name>\Sites\OfficeScan\officescan\console\HTML\widget.
- Double-click Handle Mappings under the Features View panel.
- Right-click Edit on the item for *.php.
- Update the Executable (optional): field with the correct PHP-CGI.exe:
Ensure that php-cgi.exe or PHP folder exists under PLM folder. If the file is missing, please check C:\Program Files (x86) if PHP folder and files exist. Copy the PHP folder under PLM folder.
<OSCE_Server_Installation_Folder>\PCCSRV\PLM\PHP\php-cgi.exe - Save the configuration.
- Log on to the web management console again to verify that the issue has been resolved.
