First of all, download and install Daemon Tools Lite. After the install, open Daemon Tools and a red icon will appear on your taskbar; right-click on it and go to Virtual Drive and search for an option that changes the number of drives to 1. This will make Daemon Tools create a new virtual drive on your computer. Right-click again, go to Virtual Drives, and then search for an option called Device 0; click on it and a new window will appear on your screen. Now choose the ISO file that you want to install and press OK to mount it on your HD. Now go to My Computer and do access.
