ERROR_INVALID_ACCESS - 12 (0xC)

Technical Meaning

ERROR_INVALID_ACCESS is a generic error code indicating that an operation was attempted with invalid access permissions. This error suggests that the security context or access control list (ACL) associated with the target object does not permit the requested action.

Error Details

The ERROR_INVALID_ACCESS error typically occurs when a process attempts to perform an operation on a file, directory, or other system resource without sufficient privileges. The specific details of why the access is invalid can vary depending on the context in which the error is encountered.

Usage Context

This error code is commonly used by various Windows API functions and services to indicate that the requested operation cannot be performed due to insufficient permissions. It is not tied to a specific subsystem or kernel behavior but rather serves as a generic indication of an access violation.

Developer Interpretation

When encountering ERROR_INVALID_ACCESS, developers should consider several aspects:

• Access Control Lists (ACLs): Ensure that the security context under which the operation is being performed has the necessary permissions to perform the requested action. Check if the user or process has been granted appropriate access rights.
• File and Directory Operations: Verify that the file or directory operations are being performed on valid objects. Incorrect object types can lead to this error, as certain operations may not be applicable to all types of files or directories.
• Security Context: Confirm that the security context is correctly set for the operation. Misconfigured security contexts can result in access violations.
