Failed to load cryptographic provider '%.*ls' due to an invalid Authenticode signature or invalid file path. Check previous messages for other failures.
SQL Server was unable to use the cryptographic provider listed in the error message, because SQL Server could not load the DLL. Either the name is invalid or the Authenticode signature is invalid.
Check that the file is present and that SQL Server has permission to access that location. Check the error log for additional related messages. Otherwise, contact the cryptographic provider for more information.
