Simply navigate to Utilities > Update WHMCS to begin the process.

  If the update was released recently, you may need to click the Check for Updates button before the update will show as available.
WHMCS v7.6.2 requires Ioncube Loader 10.1 or higher. The Automatic Updater verifies this requirement for you in v7.4.2.

After this, v7.6.2 will viewable and the Automatic Updater will be able to verify all requirements before proceeding to this latest version.
