JetBrains is a manufacturer of professional development tools for software developers and managers of software projects.

The JetBrains programs are available for the operating systems Windows, Linux and macOS. The first tool developed by JetBrains and probably the best known is IntelliJ IDEA, originally a development environment for the Java programming language only.

Scope and use of floating licenses of JetBrains

IT has purchased 30 floating licenses of the "All Products Pack" for DESY. The licences are managed via a licence server. The license server is called "zitlic05".

Each of these floating licenses is only valid for a certain period of time and is automatically extended for the next time frame if the license server is connected.

If there is no more connection to the license server after the time frame has expired, the user gets a popup hint that he should save his project/work and that the respective software is closed. If you would like to continue working with the program, please reconnect to the Internet and start the program again.

Release floating license again

If you are not currently using the JetBrains program, please release the license so that other users can use it.

To release a floating license, simply close the JetBrains program. This will make the floating license available to other users again.

Content of "All Products Packs"

JetBrains programs can be installed and run on Windows, Linux and macOS. Here you can see an overview with all programs included in the "All Products Pack".

Click on "Download" to the right of the corresponding program name. You will be forwarded to the download page of the manufacturer. There you can select your operating system and download the desired installation file.

Install JetBrains products

JetBrains products can be installed separately, or you can use the "Toolbox App" management tool to install and update JetBrains programs.

The Toolbox App could prove to be a convenient and clear tool for using and managing multiple JetBrains products. Furthermore, you have an overview of the JetBrains projects you have created directly in the Toolbox App.

Install each product separately

First download the desired program from the manufacturer's site (download link see contents of the "All Products Pack") and install it. You do not need administrator rights on your operating system for the installation.

The product will be activated the first time you start the program. Updates must be started and installed individually for each JetBrains product from the respective JetBrains program.

Install and manage JetBrains products using the Toolbox App

Alternatively, you have the possibility to install the management tool "Toolbox App" and manage all JetBrains products comfortably with it.

In general, the Toolbox App allows you to manage the following:

  • Install JetBrains programs
  • Uninstalling JetBrains programs
  • Installing Program Updates
  • Administration of own JetBrains projects
