ERROR_SXS_XML_E_INVALIDATROOTLEVEL - 14055 (0x36E7)

Manifest Parse Error : Invalid at the top level of the document.

Updated: Feb 21, 2026

Technical Background

The ERROR_SXS_XML_E_INVALIDATROOTLEVEL error code is associated with the Windows Side-by-Side assembly system, specifically related to manifest files. This error indicates a failure in parsing an XML document where an invalid element was found at the root level of the file.

Error Details

The numeric value for this error is 14055 (0x36E7) and it corresponds to a manifest parse error, specifically indicating that an invalid element was encountered at the top level of the XML document. This can occur during various operations involving side-by-side assemblies or manifest files.

Common Causes

  • Invalid parameter values: The XML file provided as input may contain syntax errors or incorrect elements at the root level.
  • Incorrect object type: The operation being performed expects a specific type of manifest, but an invalid or unsupported type was encountered.

Real-World Context

This error can occur in scenarios where applications or system components are attempting to load side-by-side assemblies using manifests. Manifest files are XML documents that describe the dependencies and attributes of assemblies, and any deviation from expected structure can result in this error.

Is This Error Critical?

The criticality of this error depends on the context in which it occurs. In some cases, it may be a minor issue that does not affect system functionality, while in others, it could indicate a more serious problem with the manifest file or the operation being performed.

How to Diagnose

To diagnose this error, follow these steps:

  1. Review the operation context: Determine which application or component is attempting to load the side-by-side assembly and ensure that the correct type of manifest is being used.
  2. Validate parameters: Check the XML file for syntax errors or incorrect elements at the root level. Ensure that all required attributes are present and correctly formatted.
  3. Confirm object types: Verify that the operation expects a specific type of manifest, such as an application manifest or a COM+ manifest, and ensure that the provided file matches this expectation.
  4. Verify input data: Use tools like xml.exe to validate the XML structure and identify any issues at the root level.

How to Resolve

To resolve this error, take the following actions:

  1. Correct parameter usage: Ensure that all parameters passed to the operation are valid and correctly formatted according to the expected manifest type.
  2. Adjust operation context: If the operation is being performed in an incorrect context, adjust the environment or application settings to match the required conditions for the manifest file.
  3. Restore data: If the XML file has been corrupted, restore it from a backup or recreate it with the correct structure and content.
  4. Retry operation with valid inputs: Once any issues are resolved, retry the operation using the corrected parameters and context.

Developer Notes

Developers should ensure that all manifest files used in their applications adhere to the expected XML schema and include all necessary elements at the root level. Regular validation of these files can help prevent such errors from occurring.

Related Errors

  • ERROR_SXS_XML_E_MALFORMED: Indicates a malformed XML document.
  • ERROR_SXS_XML_E_UNEXPECTEDTOKEN: Occurs when an unexpected token is found in the XML document.
  • ERROR_SXS_XML_E_MISSINGROOT: Indicates that the root element of the XML document is missing.

FAQ

Q: What does the ERROR_SXS_XML_E_INVALIDATROOTLEVEL error mean?

A: This error indicates a manifest parse failure where an invalid element was found at the top level of the XML document.

Q: How can I prevent this error from occurring?

A: Ensure that all manifest files used in your applications are correctly formatted and adhere to the expected XML schema. Regular validation of these files can help prevent such errors.

Q: Can this error affect system stability?

A: The impact on system stability depends on the context. In most cases, it is a minor issue, but if critical components are affected, it could lead to instability or failure in loading assemblies.

Summary

The ERROR_SXS_XML_E_INVALIDATROOTLEVEL error code indicates an invalid element at the root level of an XML manifest file during parsing. This can occur due to incorrect parameter values or mismatched object types. Diagnosing and resolving this issue involves validating input data, ensuring correct operation context, and adjusting parameters as necessary.
