Stalker чистое небо, в чем проблема?

Всем привет, пытаюсь запустить игру на рабочем компе с жесткими ограничениями администратора, кучу мелких проблем уже получилось решить самому, а с этой мучаюсь несколько часов, не пойму, что с этим можно сделать? При запуске игры выскакивает зеленый жук, а в логах такая картина:
