First of all, where did you download this from? Why did you download? Are you sure it's not a scam or a virus?
Second of all you shouldn't ever need to download such a thing due to Windows 7 being more or less driver
sufficient. Even if there is an odd driver missing you should ALWAYS download it directly from the manufacturers website or from the install disk that came with the device.
Just so you are aware, from reading your post I have gathered you have downloaded a dodgy ISO off the internet and intend to burn it to a CD and then do something with it. I have no idea where it's from, what drivers
they are, why you would want to do this in the first place or what your/its intentions are.
Please in future can you explain what you want us to do and what exactly you have already done.
