System requirements

JRE 1.8 is bundled with distributions for all platforms. You don't need any Java to be installed on your machine in order to run IntelliJ IDEA.

JDK is not required for developing Web, PHP, Ruby or Python projects in IntelliJ IDEA. The standalone JDK installation is required for Java development only.

However, you CANNOT use our bundled JRE for Java development.

Windows

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.

  3. Copy IntelliJ IDEA to your Applications folder.

Linux

System RequirementsInstallation
  • OS Linux 64 bit
  • 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 a different folder, if your current "Download" folder doesn't support file execution:
    tar xfz <ideaIC or ideaIU>-*.tar.gz <new_archive_folder>

    The recommended install location according to the filesystem hierarchy standard (FHS) is /opt. For example, it's possible to enter the following command:

    sudo tar xf <ideaIC or ideaIU>-*.tar.gz -C /opt/
  3. Switch to the bin directory:
    cd <new archive folder>/<ideaIC or ideaIU>-*/bin
    For example,
    cd opt/<ideaIC or ideaIU>-*/bin
  4. Run idea.sh from the bin subdirectory.
