1. Select 'Slow Download' (bottom of page)
2. A new tab called "download will be ready in a moment...." will open, close it. ("Ilivid download manager" <- don't open this! close it.)
3. Now you should be back in the kingfiles tab. Fill in the captcha and wait for the timer to hit zero.
4. There may be more pop-ups etc.. close these and you should be at (see pic).
5. Uncheck "I agree with KingFiles.net Terms & Conditions and download using recommended software", you don't need their free software, press "download now" and download will now start.
Kingfiles has alot of hoops to jump through but so do other hosts, but with KF you can usually download a new file every 5 minutes. And the speeds are much better.
You should not need to download an exe from any file sharing site.
