Note :
For devices of iR-ADV C5255 series and later, a new encryption method different from that for previous models has been adopted.
As a result, if a license encrypted by the new encryption method is downloaded by a device supporting the new encryption method, it can be installed only on devices supporting the new encryption method, and it can no longer be installed on devices supporting the old encryption method.
If a license encrypted using the new encryption method is downloaded by a device supporting the old encryption method, it cannot be installed on devices supporting the new encryption method.
