Обработчик мультимедиа CQ DAM

Я новичок в CQ, и у меня есть вопрос, относящийся к обработчику CQ DAM Media. У нас есть требование создать миниатюру для файлов необработанных форматов камеры. Я взял ссылку на приведенный ниже документ Adobe и установил imagemagicka:

http://wem.help.adobe.com/enterprise/en_US/10-0/wem/dam/dam_media_handlers.html (обработчик мультимедиа на основе командной строки)

Я могу запустить инструмент, как указано в шаге, из командной строки, но когда я редактирую модель «Dam Update Asset», она не работает и получает сообщение «ABORTED» в архиве со следующей информацией об ошибке:
