Oracle JRE 1.8 is bundled with distributions for all platforms.

JDK is not required for developing Web, PHP, Ruby or Python projects in IntelliJ IDEA.

Standalone JDK installation is required for Java development. Users can't use our bundled JDK for development.

System RequirementsInstallation
  • Microsoft Windows 10/8/7/Vista/2003/XP (incl.64-bit)
  • To develop Java applications with IntelliJ IDEA, install JDK version according to your project requirements.

    Note that you can't use JRE bundled with IntelliJ IDEA for development, only to run the IDE itself.
  1. Download IntelliJ IDEA from the Download page.
  2. Run the ideaIC or ideaIU-*.exe file that starts the Installation Wizard.
  3. Follow all steps suggested by the wizard. Pay special attention to the corresponding installation options.

OS X

System Requirements Installation
  • OS X 10.5 or higher, including 10.10
  • Only 64-bit OS X is supported.
  • To develop Java applications with IntelliJ IDEA, install JDK version according to your project requirements.

    Note that you can't use JRE bundled with IntelliJ IDEA for development, only to run the IDE itself.
  1. Download the ideaIC or ideaIU-*.dmg OS X Disk Image file from the Download  page.
  2. Double-click the downloaded ideaIC or ideaIU-*.dmg OS X Disk Image file to mount it.
  3. Copy IntelliJ IDEA to your Applications folder.

Linux

System RequirementsInstallation
  • OS Linux
  • KDE, GNOME or Unity DE desktop
  • To develop Java applications with IntelliJ IDEA, install JDK version according to your project requirements.

    Note that you can't use JRE bundled with IntelliJ IDEA for development, only to run the IDE itself.
  1. Download the ideaIC or ideaIU-*.tar.gz file from the Download page.
  2. Unpack the ideaIC or ideaIU-*.tar.gz file to an empty directory using the following command: 
    tar xfz ideaIC or ideaIU-*.tar.gz
  3. Because running IntelliJ IDEA from wherever you downloaded the file to may be inconvenient, it is recommended that you move the extracted or unpacked archive folder to the desired location using the mv command in one of the following formats: 
    • mv <path to extracted archive folder> <new archive folder>
      For example: 
      mv /downloads/ideaIC or ideaIU-* my/desired/location
    • mv <path to ideaIC or ideaIU-*.tar.gz> <new archive folder>
      For example: 
      mv /downloads/ideaIC or ideaIU-*.tar.gz my/desired/location
  4. Switch to the bin directory in the new location: 
    cd <new archive folder>/ideaIC or ideaIU-*/bin
    For example, 
    cd my/desired/location/ideaIC or ideaIU-*/bin
  5. Run ideaIC or ideaIU.sh from the bin subdirectory.
