|Try installing the trial version of MagicIso. Use MagicIso to open the .img file and save as another format (e.g. iso).|
Or, if it opens in MagicIso, you can just extract all files to a folder on your hard drive.
If MagicIso won't open it, chances are you ended up with a corrupted download. Try downloading again. I just tried downloading it and had the same problems.
Try downloading this zip file. It works for me.
