Try to set the Management Service schema license key with command as shown below:

CAST-MS-CLI.exe ConfigurePlatformPreferences -connectionProfile "xxxxx_mngt on CastStorageService _ YYYXXX:2280" -licenseKey "xxxxx" -sourceDeliveryFolder "C:\CAST\Delivery"
-sourceDeploymentFolder "C:\CAST\Deploy" -logRootPath "C:\CAST\Log"

The command mentioned in step by step scenario, is used to set the License as well as Delivery and Deployment Folder of CAST MS.

The error in question is encountered if the Deliver and Deployment folder is already set.
Since delivery and deployment folder is already set, so the solution is to

1. Only update the license and not delivery and deployment folder with below comment.

   CAST-MS-CLI.exe ConfigurePlatformPreferences -connectionProfile "<profile>" -licenseKey "<xxxxx>"

Impact of error : License key is not set
Impact of solution: None
