Signature mismatch for the file "install_flash_player.exe"

[Billhwang163]

Hello, Recently we have an issue when run the "Install required updates and fix vulnerabilities" task, most of the new application updates could be updated successfully, but the Adobe flash player with the "signature mismatch" error as shown in the screenshot. I can manually download the files (install_flash_player.exe) by IE and Firefox on the KES server. Does anybody has the similar issue? thanks in advance for any comment.

Я нашел решение, до которого, видимо, не дошел сам Kaspersky. Дело в том, что одна из версий, предлагаемых для пошагового обновления потеряла цифровую сигнатуру, всё, что необходимо сделать - пропустить предыдущие версии. Необходимо в параметрах задачи выбрать Параметры, свойства правила, обновления, Устанавливать только обновления из списка и выбрать необходимую вам версию. Так же не забудьте снять снизу галочку устанавливать все необходимые для установки приложения. Бинго!

Ещё поправка. Проверьте устанавливаемое обновление. У меня не обновляло WinRar version, однако version x64 установило
