You need to download a virtual cd/dvd drive called DAEMON Tools
Get the older version 3.47
When you install it, load the .iso file into it, and it will automatically run the program..... that's if it has an autorun file in it.
Also, if you were familiar with .iso files, you could use a burner software like Nero or others, and it'll burn the .iso file to disc for you. What will happen is the files inside of the .iso will get extracted and tranferred to disc automatically.
And for future references, an .iso is nothing more than a .zip , .rar type compression. That's all it is, compressed files/folders.
