The error message comes directly from the underlying Flexera licensing system. We have checked the code, but it is not really helpful. So I would recommend these steps:
Delete the folder corresponding to your dongle ID on the target system in C:\NexeedLocal\Licenses.

Restart the target system and start the workflow again.
