Why I received error C0 eventhough I had successfully generate the update file?

Symptom: Successfully generate the update file with the mother dongle. When try to update the child dongle with update tool, I received error C0.

Problem: Error C0 when try to update the dongle with update tool.

Solution:

On our License Manager, before you create the update file, you need to generate the same key pair with the dongle you want to update later.

For e.g:
1. Mother dongle generate a new key pair (Key Pair A)
2. Generate update file
3. Client dongle restores the same Key Pair A
4. Client dongle use the update tool to update the dongle

If you generate new key pair(for e.g Key Pair B), and update the file generated with key pair A generated by the mother dongle, it will caused an error 0xC0.
