How to find the license file or information used by the IDE

The active license can be observed in the Help | Register dialog or Register link at the bottom of the product Welcome Screen (when there is no project open).

When using JetBrains Account or the new offline activation key, information is encrypted and is stored in the system registry, therefore there is no easy way to access it and copying it to another system will not work (a machine-specific token is used).

When using the license server, it's stored in the <product><version>.key file under the IDE configuration directory.

Please note that this file has UCS2 (2-byte Unicode) encoding and you can't view it in basic editors like Notepad, you need to open it in a Unicode-aware editor.
