The PC-Locked License cannot be registered and downloaded from the normal registration site. In order to register and download a PC-Locked license, you must install Noah System 4 as usual and start up with the temporary license. When you see the Unlicensed Noah dialog, click on the Register your Noah License button.
You can now register and download the license file.
IMPORTANT: If you are trying to register a PC-locked license after the Evaluation Period is over, click here for instructions.
