If your vendor provided you a Computer ID key. This key must be installed before you can produce a locking code.
An application or License Manager may be restricted to operate on certain computers. These restrictions are included in the license codes when they are created.
Before your vendor creates a license code with any computer restrictions, you must get the locking code for your computer with the echoid program. Your vendor will tell you which computers you must run echoid on. The echoid utility outputs either one or two hexadecimal locking codes depending upon how your vendor has configured it. You will send all locking information to your vendor. Your vendor will use this information, which is specific to your computers, to generate new license codes.
