Updated: Feb 21, 2026
Technical Meaning
The error code RPC_X_WRONG_STUB_VERSION indicates that there is a version mismatch between the client and server stubs in a Remote Procedure Call (RPC) context. This typically occurs when an application attempts to communicate with a service using a different version of the RPC stub than what was expected.
Error Details
The error code 1829 corresponds to 0x725 in hexadecimal notation. It is returned by the Windows API when the client and server stub versions do not match, leading to an incompatible communication scenario.
Usage Context
This error can occur in various scenarios where RPC-based services are used, such as networked applications or distributed systems that rely on inter-process communication (IPC) over a network. The mismatch might be due to updates or changes in the service provider's codebase without corresponding updates in the client application.
Developer Interpretation
When encountering this error, developers should ensure that all components involved in the RPC communication are using compatible versions of the stubs. This includes verifying that both the client and server applications have been updated correctly to maintain version consistency.
