FOR THE THIRD TIME NOW.... PLEASE READ!!!!!! When you add a language pack into a normal windows 7 image i.e. Ultimate. It will automatically mount the boot.wim and add the required files so that you can select that language during install. You DO NOT have to mount the boot.wim manually and add the packages. This will be the last time I will be replying to this thread. Besides your above issue is DISM/PKGMGR related so there is nothing i can do about it anyway...
