I've rebooted numerous times and I've also tried running it from that PC, from a network drive and from a USB drive ("Run as Administrator" does NOT work either).

After starting the "tool", I've even let the PC sit overnight to see if it would ever start to run. I've spent the better part of the last four days trying to get the Windows 10 upgrade installed on my desktop. I know it does not start immediately but I have successfully run it on two other PCs with Windows 8.1. When I try to run it, nothing happens after clicking the message that allows it run.

The Media Creation Tool will NOT run at all on my Windows 7 Ultimate desktop and my Lenovo Yoga 2 Pro with Windows 8.1.
