unable to install

I have downloaded the windows 10 update, but unable to install. Can I install through downloaded flies manually?

 

Yikes. The download would take roughly 16 hours.

Do you have a friend who could download the .iso from:

Windows 10

It'd be perfectly legal, and give you the same upgrade as the "reserved" copy.

 

the download is complete, it took 17 hours

but now its stuck at preparing for installation!!!
