You shall see this dialog when your node-locked license is registered successfully:
or this dialog if failed:
Please contact me on the failure, chances are you provided the wrong user request code, or I send you the wrong registration code, or simply you pasted the wrong registration code. Sometimes I send the code in the form of "user code > registration code":
PICKER-WIN-02P0-7363-4BED-0D31-124E-1431 > PICKER-WIN-02P0-####-####-####-####-####-####-####-####-####-####-####-####
The code you need to copy and paste into the registry dialog is the one after ">", not the full string.
