Hi I am using Windows 8.1 Update Enterprise 64 bit and Windows ADK. I noticed that, if I select the "Environment of the deployment tools and creations images" and I click on the "Run as Administrator" item of his Pop-Up menu and I mount on a iso image of windows 8.1 Update, when I run the command robocopy <Drive_Letter>:\"<Windows_Files_Path>" /e to copy all its files in a directory and the command dism /Mount-Image /ImageFile:"<Windows_Files_Path>"\install.wim /Index:<Image_Index> /MountDir:"<Mount_Directory_Path>" to mount an image volume, this error appears: Error: 0xc1510111Not have permission to mount and modify this image. However, if I copy these files through the "file explorer" window, the mounting of this volume image is working properly. How come? Thanks Bye
