Updated: Feb 21, 2026
Technical Meaning
The ERROR_SXS_INVALID_IDENTITY_ATTRIBUTE_VALUE error indicates that a value assigned to an attribute within an identity is outside the permissible range. This error typically arises in scenarios involving side-by-side assemblies and their manifest files.
Error Details
This error code, 14090 (0x370A), signifies that there has been an attempt to use a value for an attribute that does not conform to the expected or allowed range. The specific attribute in question is part of an identity used within the side-by-side assembly framework.
Usage Context
This error can occur during the loading and execution of assemblies managed by the Side-by-Side (SXS) engine, particularly when there are issues with manifest files or metadata associated with these assemblies. The SXS engine relies on strict validation to ensure that all identities used in side-by-side assemblies adhere to predefined rules.
Developer Interpretation
When encountering this error, developers should focus on validating the values assigned to attributes within their assembly manifests and ensuring compliance with the specified ranges. This includes checking for correct attribute names, valid value types, and adherence to any versioning or compatibility constraints imposed by the SXS framework.

FAQ
Q: What does this error mean?
A: This error indicates that an attribute value in a side-by-side assembly manifest is outside its legal range.
Q: How can I resolve this issue?
A: Review and correct the values assigned to attributes within your assembly manifests. Ensure they fall within the allowed ranges as defined by the SXS framework.
Summary
The ERROR_SXS_INVALID_IDENTITY_ATTRIBUTE_VALUE error is a specific technical issue related to attribute validation in side-by-side assemblies. Developers should focus on ensuring that all manifest file entries adhere to the correct format and value ranges to avoid this error.
