Discontinued features

  • Support for Linux 32-bit is discontinued. No installation package will be provided in future. 
  • PHP 5.x built-in binaries for running and debugging CLI applications are not provided anymore. Only a single PHP built-in binary with the latest PHP version will be provided. Custom PHP binaries can still be added via the preference page.
  • The Amazon AWS Toolkit extra feature is discontinued. It was a fork of an old version of the plugin. We recommend to use to genuine plugin provided by Amazon:  
  • The OpenShift integration is discontinued.
  • The VMWare Workstation Support extra feature is discontinued.

System Requirements

  • Supported Operating Systems:
    • Windows 7, Windows 8.1, Windows 10
    • Linux x86-64
    • OS X 10.10 Yosemite, 10.11 El Capitan
  • 1.5GHz processor
  • 2GB RAM
  • 1GB of hard disk space

PHP 7 built-in executables (Windows only)

  • The PHP 7 built-in executables require the Visual C++ Redistributable for Visual Studio 2015 (x86 variant) to be installed in the operating system. The installer of Zend Studio 13 and later installs it automatically, but users upgrading from earlier Zend Studio version must install it manually from here:

Apigility integration requirements

  • Internet Explorer >=10 is required on Windows for the Apigility Editor to render correctly.

Mobile development requirements

Code Trace requirements

  • Flash Player must be installed in the operating system.

Known Issues

  • Update to Zend Studio 13 or newer from older versions is not supported on Mac OS X. New installation of Zend Studio 13 or newer is required. If an update is attempted, this will corrupt the Zend Studio installation.

  • CordovaSim requires manual configuration of JRE (Mac OS X only). For some reason the Eclipse Platform on Mac OS X does not automatically configure the JRE that runs Studio. Users must manually configure it in the Java > Installed JREs preference page.

  • Reset Perspective may be required after installation of the Terminal plugin. This is required in case it does not appear in the Show In context menu.

  • During update of Studio a security warning about unsigned content may be shown. You can safely ignore this warning and proceed with the upgrade.

  • Z-Ray may not render correctly inside Zend Studio on Windows. A workaround can be applied in one of the following alternative ways:

    • Modify Zend Server configuration to include the X-UA-Compatible: IE=edge HTTP header in the response. If Zend Server is running on Apache HTTP Server then:
      • Add the following line in the httpd.conf file:

        Header add X-UA-Compatible "IE=edge"
      • Restart the Apache HTTP Server.

      • Reopen the web browser inside Zend Studio.

    • Modify the application to include "X-UA-Compatible: IE=edge" HTTP header in the response:
      • Add the following line in a suitable place in your PHP code:

        header("X-UA-Compatible: IE=edge");
      • Reopen the web browser inside Zend Studio.

    In Zend Server 8 and later Z-Ray will automatically add the "X-UA-Compatible: IE=edge" HTTP header in the response, so the above workaround will not be required.

  • Zend Debugger PHP extension is not available for PHP builds with Thread Safety enabled. You can find out the status of Thread Safety in your PHP:

    • in phpinfo() output
    • by checking the value of the predefined constant PHP_ZTS ("false" means Non Thread Safe, i.e. supported by Zend Debugger) If you use Thread-Safe PHP, consider Xdebug as the alternative.
  • Zend Studio Crashes with Segmentation Fault in KDE 4.11 and newer, see

  • Zend Studio menus do not show or appear only partially in the menu bar of Ubuntu 13.10 and 14.04. The issue is caused by Ubuntu's bug See         

  • To display class inheritance charts in the documentation generated by PHPDocumentor installation of Graphviz is required. Due to compatibility issues, please install:
