For those of you who don't know, you may run an .iso file directly, as it it were an executable, with Magic ISO.

• Get Magic ISO here.
• You will also need this.
• Right click on the .iso file. Pick the first option under the MagicISO menu which starts with "Mount" and then the first/only option that appears under the next submenu that flys out.
• This will associate the .iso with a drive letter, perhaps the E drive for example. Just navigate to the drive via "My Computer" to run the .iso.
• When finished, right-click on any file and pick "Unmount all drivers" from the MagicISO menu.
