ERROR_SXS_MANIFEST_TOO_BIG - 14105 (0x3719)

The size of the manifest exceeds the maximum allowed.

Updated: Feb 21, 2026

Technical Background

The ERROR_SXS_MANIFEST_TOO_BIG error code indicates that a software component, specifically one managed by the Side-by-Side (SXS) assembly loader, has attempted to load a manifest file that exceeds the maximum allowable size. This limitation is enforced to prevent excessive memory usage and ensure system stability.

Error Details

The ERROR_SXS_MANIFEST_TOO_BIG error code is returned when the SXS assembly loader encounters a manifest file that is larger than the predefined threshold. The exact threshold can vary depending on the version of Windows, but it generally limits the size to prevent potential issues such as excessive memory consumption or performance degradation.

Common Causes

  • Excessive Manifest Data: The manifest file contains more data than allowed by the system's configuration.
  • Incorrect Manifest Usage: The manifest is being used in a context where its size exceeds the allowable limit.

    Real-World Context

    This error can occur during the loading of assemblies or components that are part of larger software systems. For example, it might be encountered when deploying applications with extensive metadata or complex configurations.

    Is This Error Critical?

    The ERROR_SXS_MANIFEST_TOO_BIG error is generally not critical to system stability but may indicate a need for optimization in the manifest file or the application's deployment strategy.

    How to Diagnose

    1. Review Manifest File: Inspect the manifest file to identify any excessive data or redundant information.
    2. Validate Parameters: Ensure that all parameters passed to the SXS assembly loader are within acceptable limits.
    3. Check System Limits: Verify that the system's resource limits, particularly memory constraints, are not being exceeded.

      How to Resolve

    4. Optimize Manifest File: Remove unnecessary data or optimize the manifest structure to reduce its size.
    5. Adjust Deployment Strategy: Modify how assemblies and components are deployed to ensure they do not exceed the allowable manifest size.
    6. Retry Operation: After making necessary adjustments, retry the operation that triggered the error.

      Developer Notes

      Developers should be aware of the maximum allowed manifest size when designing applications or deploying software components. Ensuring that manifests are kept within these limits can help prevent such errors and improve system performance.
