This error is caused by one of the following issues:
- There are extra characters in the license key string. Check to make sure there are no extra characters at the beginning of the license key, and that the key ends in == with no trailing space.
- The time on the NetSight server is incorrect. If the time on the NetSight server is before the creation date of the license it will not apply correctly.
- The license key is incorrect, or not complete.
