Error message: "Failure - Could not download Normalized Manufacturer Names" Issue While attempting to download manufacturer names using the Guided Setup for Normalization Data Services, you are seeing the error message "Failure - Could not download Normalized Manufacturer Names"ReleaseAll releases - Developer instancesResolutionThe developer instances are intentionally designed to not support this functionality. Since this is a subscription dependent feature and the tables can easily be imported and exported on other instances after the normalization, it has been decided to disable it on developer instances. This is allowed only on sub-production and production instances.
