For some reason it doesn't see the .iso as a burnable disk or it doesn't "see" the iso at all. Is it really an .iso or did you download the .exe by mistake? The .exe can only be used while booted in Windows.
Is it an upgrade version, you need the full version for Boot Camp Assistant?

You can burn it yourself first with "Disk Utility" at 2x only speed if you can't get it going.
Heres a link for more information. Here's an excerp from@Noble Seven's response:
Ok, that is wrong. To burn the iso to a disk, you first need to open the Disk Utility program, which is in the Utilities folder in Applications. If your cd is inside the computer, you should see it in the left pane. Select it. At the top, you will see the biohazard symbol that says "Burn". Select that, and find the iso file on your computer, and burn it.
It should now work fine.
With the Retail Upgrade DVD version, (in 10.6) I could still do a clean install. I don't know if you can with a burned "Upgrade" iso image.
