Install OmniStudio Package in Salesforce Enterprise Edition Q/A

This error typically occurs when there is no appropriate license for the OmniStudio package. Check if standard objects with the name "OmniXXX" (including OmniProcess and OmniUiCards) exist in the respective org. If not, it means that the licenses have not been properly provisioned.

OmniStudio licenses need to be activated prior to running the package installation. Activating the licenses will create the OmniStudio standard objects. The OmniStudio license names start with "OmniStudio".
