It is the 7th step after drivers: components u would like to remove. I've selected "help engine". Completed other steps (I've chosen fully automated unattended mode), and burned the iso. After that when I start installing my windows. I format the disc into ntfs. Then windows starts copying files from the cd. As soon as it finds some .chm files it brings the error, and 3 choices - to push F3 - to exit setup, ESC to skip copying this file and ENTER to try copying this component again.
