You can evaluate the trial version of CLion for up to 30 days. After that, you need to buy and register a license.
Do one of the following to open the License Activation dialog:
On the Welcome screen, click
On the main menu, select
Select how you want to register CLion:
Register using the JetBrains Account.
For more information, see What is JetBrains Account?
Register using an activation code.
Register using a License Server.
To override the URL of the system proxy during initial CLion startup, use the
-Djba.http.proxyproperty, which can be added as a JVM option.
When performing silent install or managing CLion installations on multiple machines, you can set the
JETBRAINS_LICENSE_SERVERenvironment variable to point the installation to the license server URL.
If you have plugins that require a license, then instead of the License Activation dialog, open the Licenses dialog by clicking from the main menu.
The Licenses dialog contains a list of licenses and shows their states:
Expired: Renew your license to continue.
Grace period: You have several days until the license expires.
Evaluation period: Use without an active license.
Active license: Use until the expiry date.
To configure a license, click the Edit button, which opens the License Activation dialog.
