Updated: Feb 21, 2026
Technical Meaning
This error code indicates a specific issue encountered during the parsing of an XML manifest file. The error suggests that there is an unclosed comment within the XML structure, which can disrupt the proper processing and interpretation of the manifest.
Error Details
The ERROR_SXS_XML_E_UNCLOSEDCOMMENT error occurs when the synchronization services (SXS) encounters a malformed XML document where a comment tag has not been properly closed. This can lead to parsing failures or incorrect behavior in applications that rely on these manifests for configuration and resource loading.
Usage Context
This error is typically encountered during the initialization of components managed by the Synchronization Services, such as assemblies and manifest files used in .NET Framework applications or Windows modules.
Developer Interpretation
Developers should ensure that all XML documents, particularly those used in manifests, are well-formed. This includes properly closing all tags, including comments, to avoid runtime errors and ensure consistent behavior across different execution contexts.
