Cause

  1. Custom PHP is used.

Resolution

  1. Make sure that there is no custom PHP settings in registry ( HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\PHP ). Example of custom installation:

        [HKEY_LOCAL_MACHINE\\SOFTWARE\\Wow6432Node\\PHP]
    "InstallDir"="D:\\\\PHP\\\\"
    "Version"="5.3.3"
    "WebServerType"="iis4FastCGI"

    If there is, it is better to uninstall custom PHP (if it is not used) or rename directory (e.g. D:\\PHP\\ ) if uninstallation is not acceptable at the moment.

  2. Delete any custom PHP environment variables (if they exist):

    • Right-click My Computer , and then click Properties .
    • Click the Advanced tab.
    • Click Environment variables .
