ERROR_INVALID_IMAGE_HASH - 577 (0x241)

Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.

Updated: Feb 21, 2026

Technical Background

The ERROR_INVALID_IMAGE_HASH error code is a specific error that indicates an issue with the digital signature verification of a file. This error typically arises when Windows fails to validate the integrity or authenticity of a file's digital signature, suggesting potential corruption or tampering.

Error Details

  • Error Name: ERROR_INVALID_IMAGE_HASH
  • Numeric Code: 577 (0x241)
  • Short Description: Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.

Common Causes

This error can occur due to several reasons:

  • Corrupted File: The file may have been corrupted during transfer or storage, leading to invalid digital signature data.
  • Incorrectly Signed File: The file could have been signed incorrectly by the developer or publisher, resulting in an invalid hash value.
  • Malicious Software: A malicious entity might have tampered with the file, altering its contents and thus its digital signature.

Real-World Context

This error is particularly relevant when dealing with executable files (.exe, .dll) that require a valid digital signature for security reasons. The presence of this error can indicate potential security risks or issues with the integrity of the file.

Is This Error Critical?

The criticality of this error depends on the context in which it occurs. If the file is part of a system component, such as a driver or an essential application, the impact could be significant. However, if the file is not critical to the operation of the system, the impact may be minimal.

How to Diagnose

To diagnose this issue, follow these steps:

  1. Review Operation Context: Determine whether the file in question is part of a known good installation or update process.
  2. Validate Parameters: Ensure that all parameters passed during the operation are correct and valid.
  3. Confirm Object Types: Verify that the object being operated on (file, directory) is of the expected type.
  4. Verify Input Data: Check if the file has been modified or corrupted since its last known good state.
  5. Check Limits or Constraints: Ensure that no system limits have been exceeded during the operation.

How to Resolve

To resolve this issue, consider these practical steps:

  • Correct Parameter Usage: Ensure all parameters are correctly specified and passed to the relevant functions.
  • Adjust Operation Context: If the file is part of an update or installation process, ensure that the source of the files is trusted and verified.
  • Restore Data: If the file has been corrupted, restore it from a known good backup or re-download it from a trusted source.
  • Retry Operation with Valid Inputs: Attempt to perform the operation again using valid inputs to see if the issue persists.

Developer Notes

Developers should ensure that all files distributed are properly signed and validated before installation. Additionally, they should implement robust error handling mechanisms to gracefully handle such errors during runtime.

Related Errors

  • ERROR_FILE_NOT_FOUND (2): This error might occur in conjunction with ERROR_INVALID_IMAGE_HASH if the file is missing or inaccessible.
  • ERROR_BAD_EXE_FORMAT (1168): This error can indicate issues related to executable format, which may also be associated with invalid digital signatures.

FAQ

Q: What does the ERROR_INVALID_IMAGE_HASH mean?

A: It indicates that Windows failed to verify the digital signature of a file, suggesting potential corruption or tampering.

Q: How can I prevent this error from occurring?

A: Ensure all files are properly signed and validated before installation. Use trusted sources for downloading and updating software.

Q: Is this error critical?

A: The criticality depends on the context. If the file is part of a system component, it could be significant; otherwise, it may not have severe consequences.

Summary

ERROR_INVALID_IMAGE_HASH (577) is a specific error indicating issues with digital signature verification in Windows. It can arise due to corrupted files, incorrectly signed files, or malicious tampering. By following the diagnostic and resolution steps outlined above, developers and system administrators can effectively address this issue.
