ERROR_SXS_ASSEMBLY_NOT_LOCKED - 14097 (0x3711)
The component must be locked before making the request.
Updated: Feb 21, 2026
Technical Meaning
The ERROR_SXS_ASSEMBLY_NOT_LOCKED error code indicates that an attempt was made to perform an operation on a component, specifically an assembly in the Side-by-Side (SXS) store, without first locking it. Locking is necessary to ensure consistency and prevent concurrent modifications.
Error Details
This error typically occurs when a developer or system attempts to modify or access an assembly within the SXS store without having acquired the appropriate locks. The SXS store manages assemblies in a way that requires explicit locking mechanisms to maintain integrity and avoid race conditions during operations such as loading, unloading, or updating assemblies.
Usage Context
This error is relevant primarily when dealing with the Side-by-Side (SXS) assembly store on Windows operating systems. It can be encountered in scenarios where an application or system service attempts to modify an assembly while other processes are also accessing it.
Developer Interpretation
When encountering this error, developers should ensure that they have correctly managed locks around operations involving assemblies within the SXS store. This includes acquiring and releasing locks appropriately during assembly loading, unloading, or modification tasks. Failure to do so can lead to inconsistent states and potential data corruption.
Related Errors
ERROR_SXS_ASSEMBLY_LOCKED(14098): Indicates that an attempt was made to unlock a component that is still in use.ERROR_SXS_COMPONENT_STORE_CORRUPT(14063): Suggests issues with the integrity of the assembly store, which might indirectly lead to locking errors if the store itself is corrupted.
FAQ
Q: What does this error mean?
A: This error indicates that an attempt was made to perform an operation on a component in the SXS store without first acquiring the necessary locks. Locking is required to ensure consistency and prevent concurrent modifications.
Q: How can I resolve this issue?
A: Ensure that you have correctly managed locks around operations involving assemblies within the SXS store. Acquire and release locks appropriately during assembly loading, unloading, or modification tasks.
Summary
The ERROR_SXS_ASSEMBLY_NOT_LOCKED error code is a specific technical indicator used by Windows to enforce proper locking mechanisms when interacting with components in the Side-by-Side (SXS) store. Ensuring correct lock management is crucial for maintaining the integrity and consistency of assemblies within this store.
