Releasing Licenses

Windows

The procedure to revoke a license on Windows depends on the product version. The product version can be checked from the About dialog on the Help menu.

    If the version number is 7.0 enhancement 7 or greater, or the version is greater than 7.0
    Uninstall the ionCube Encoder software and follow any instructions given. If the computer is connected to the Internet, the license should be removed automatically.

    If the version is 6.5 enhancement 16 or greater, or 7.0 with enhancement number less than 7
    Uninstall the ionCube Encoder. Send the revoke_file.txt revoke file created in the licensing folder to licenses@ioncube.com

    If the version is less than 6.5 or the version is 6.5 with enhancement less than 16
    Use the delete license feature from the "ionCube PHP Encoder" Windows program menu. Note that on Windows systems from Vista onwards, the script must be run with administrator privileges by right clicking on the delete license program and selecting "Run as administrator". Send the revoke file created in the installation folder of the Encoder to licenses@ioncube.com


OS X with GUI (8.2 onwards)

Use the Release License option on the Help menu and follow the instructions.
Other Platforms (e.g. Linux)
Version 8 or greater

The license can be released automatically over the Internet by using the --release-license command line option. Alternatively, use the --gen-revoke option and a file will be created for sending to licenses@ioncube.com for processing.
Before version 8

Run the Encoder with the --revoke option in the Encoder installation directory and send the revoke file to licenses@ioncube.com
