CO_E_WRONG_SERVER_IDENTITY

CO_E_WRONG_SERVER_IDENTITY means that COM found an identity conflict while resolving the class server. The problem is not a general file-permission failure: it concerns the security identity configured for the COM application and the identity or activation context required for this request.

Identity is part of COM activation

Out-of-process COM servers can be associated with an AppID. That AppID centralizes deployment and security settings, including RunAs, while service-hosted servers use LocalService and the service’s own account configuration. A class that is intentionally configured for one identity should not be treated as interchangeable with the caller’s process identity.

How to diagnose without weakening the setup

Identify the CLSID, then inspect its AppID association and the selected server model: executable, service, or remote server.
Compare the configured identity with the required deployment model before changing credentials or DCOM permissions.
Separate this result from CO_E_RUNAS_LOGON_FAILURE, which concerns failure to log on with a configured identity, and from launch-permission denial, which concerns authorization of the client.
