CLion 2021.3 Help

Register

You can evaluate CLion for up to 30 days. After installing the IDE, log in to your JetBrains Account to start using the CLion's trial version.

Start the free trial

  1. In the Licences dialog that opens when you start CLion, select the Start trial option and click Log in to JetBrains Account. You will be redirected to the JetBrains Account website.

  2. Log in to your JetBrains Account on the website and click Start Trial in the Licences dialog to start your trial period.

Upon the expiration of the trial version, you need to buy and register a license to continue using CLion. A new trial period will be available for the next released version of CLion.

    • From the main menu, select Help | Register

    Option

    Description

    JB Account

    Register using the JetBrains Account.

    If you use two-factor authentication for your JetBrains Account, specify the generated app password instead of the primary JetBrains Account password.

    JetBrains Account with 2-factor authentication

    Activation code

    Register using an activation code.

    You can get an activation code when you purchase a license for the corresponding product.

    License server

    Register using the Floating License Server.

    When performing silent install or managing CLion installations on multiple machines, you can set the JETBRAINS_LICENSE_SERVER environment variable to point the installation to the Floating License Server URL.

    Alternatively, you can set the Floating License Server URL by adding the -DJETBRAINS_LICENSE_SERVER JVM option.

    CLion detects the system proxy URL during initial startup and uses it for connecting to the JetBrains Account and Floating License Server. To override the URL of the system proxy, add the -Djba.http.proxy JVM option. Specify the proxy URL as the host address and optional port number: proxy-host[:proxy-port]. For example: -Djba.http.proxy=http://my-proxy.com:4321.

    If you want to disable proxy detection entirely and always connect directly, set the property to -Djba.http.proxy=direct.

Access to JetBrains Account: Troubleshooting

If you encounter problems when attempting to log in to your JetBrains Account, this may be due to one of the following reasons:

No free ports

CLion waits for a response about successful login from the JetBrains Account website. If there are no ports available, CLion will suggest logging in with an authorization token.

Unable to open JetBrains Account in your browser

When you click Log in to JetBrains Account, CLion redirects you to the JetBrains Account website. If your system browser doesn't start, use the Troubles emergency button. CLion will suggest logging in with an authorization token.

No access to JetBrains Account

The login process requires access to the JetBrains Account website. CLion automatically redirects you to the website or lets you log in with an authorization token. If both options don't work and you cannot access the website, contact your system administrator. Otherwise, it will not be possible for you to log in and start using CLion.

Log in with an authorization token

An authorization token is a way to log in to your JetBrains Account if your system doesn't allow for redirection from the IDE directly, for example, due to your company's security policy. CLion recognizes when redirection to the JetBrains Account website is impossible. It enables you to copy a link to generate an authorization token manually.

  1. Click Copy link and open the copied link in your browser.

  2. Log in to your JetBrains Account to generate an authorization token. After that, copy the token, paste it to the IDE authorization token field and click Check token. Once you've successfully logged in, you can start using CLion.
