OK, let's see if I can explain. When you download an ISO file from My Digital Life or Digital River or any of the Linux distributors it comes as one big file - a bit like a big ZIP file. You cannot install or run anything from a ZIP file, it has to be 'unzipped' first, and it is the same with an ISO file except that applications like Winzip, Winrar and 7-zip won't work in this case. This is why you need an application like ImageBurn because it is capable of opening out all the files that are wrapped up inside the ISO file.
It may be that My Digital Life prefer a different application to ImageBurn, but you would still have to go through the process somehow.
Assuming that for some reason Windows will not boot on your computer, and you cannot fix the problems by means of 'Safe mode' (normally tap the 'F8' key a few times while the BIOS screen is showing, then select one of the 'Safe mode' options, usually 'Safe mode with networking') then you need either a Windows repair disc or a Windows install disc. Note that the Windows repair disc comes in two varieties - 32 and 64 bit - and you need the correct one for your system.
You can get instructions for making a repair disc from BC, here -
If the repair disc doesn't work for you, then, assuming you have a valid Win 7 authentication key, you can download an install copy of Win 7 from Digital River and here are the relevant links. Do note that this install copy DOES come to you as an ISO file and will need to be opened up to normal files with something like ImageBurn before you can use it. :-
