IntelliJ IDEA 12.1.0 Web Help

Some features described here are available in Ultimate edition only.

IntelliJ IDEA is provided in two editions: Community and Ultimate. For using the Community edition no license is required at all. The Ultimate edition is available in its trial version for 30 days, whereupon you need to obtain and register a license.

IntelliJ IDEA provides several types of licenses, to flexibly meet the demands of the customers. In particular, these are: personal, commercial, academic, classroom, and open-source licenses. You can find the detailed information about licensing terms at the Licensing and Upgrade page.

Troubleshooting

A license key can be rejected by the software in certain cases. The table below outlines the reasons of license rejections, and the possible ways to solve the problem.

ReasonSolution
Wrong user nameMake sure that you are using the User Name which is specified in your license certificate email. If a license is registered in your company name, it will not work with your personal name.
Misspelled User Name/License KeyTo avoid misspellings, we recommend that you copy your User Name and license key from the license certificate e-mail rather than enter them manually in the software. You can do so by using the Ctrl+C; Ctrl+InsertCtrl+C; Ctrl+Insert and Ctrl+V; Shift+InsertCtrl+V; Shift+Insert shortcuts.
A license key does not qualify for upgrade to a higher versionIf your license key does not work with the newly installed version of the software, please make sure that your current license key allows you to upgrade for free to the latest version. If it does not, please contact sales (sales@jetbrains.com) in order to upgrade your license.
Concurrent use of a license keyMake sure that your license key is not being used by another developer in your company at the same time. Concurrent use of a single license on multiple instances of the software is restricted by our software license agreements (unless you have obtained a floating license) and is prevented by software functionality.
