Problem:
Windows 10 Tecnnical Preview: We ran into an installation error. This might be because your PC doesn't meet system requirements or your language isn't available.
Reason:
I had Windows 8 Pro, upgraded to Windows 8.1 Pro. But I have not updated Win 8.1 yet to the most current.
Solution:
1. Upgrade Window 8.1 first, then run the installation of Windows10TechnicalPreview
2. Download the ISO file, then run it.
