Windows 8 Upgrade download failed. Alternative download method?

I bought the Windows 8 Upgrade Promo for $14.99 for my HP Envy 4 Windows 7 Home Premium 64-bit just today. But when I got to the download step, it fails; it doesn't even start. It just checks or so the message says then gives me the following message:

The Download did not complete successfully
The download task did not complete.

The data is invalid.

I have tried several times with the same result.

I've read some forums and some say it's the wireless/mobile network problem? but I'm not sure. Something about the file being too big but I am sure I've downloaded much bigger files. I am using a 3G mobile internet connection from my iPhone hot spot. Currently, I am limited to using it and all internet connections in our area are mobile/cellular so I have no way around it.

Is there an alternative way of downloading Windows 8 for upgrade? Is there a Win8 installer in the microsoft website that can be used for upgrading from Win7?

The Upgrade Assistant is the only method of downloading Windows 8.

Which browser are you using?

Try to rename or delete the WebSetup folder and try again.
