You dont need that img file. Nlite will create the bootable ISO, if you select it in Nlite. All you have to do, is select the drivers, if you want to slipstream any. And select the options you dont want to install (after Nlite creates the ISO).I would also use RVM Integrator. It makes things a lot easier. So install both of these.. Use Nlite first. Then run RVM Integrator. Then add this update first. Altho, most of the links there are rubbish.I would get this one. Then add it under updatepack in RVM integrator. You can also remove the files (that the update adds that you dont want). I think you need that img file if you use Nero, but you dont need it if you use Nlite
