Windows Phone SDK8 installation troobleshooting

I was using Visual Studio 2012 + SDK 8.0 on a PC running Windows 8 (not pro), and I decide to buy another hard drive to install Windows Pro on the sam PC in order to run a Windows Phone emulator on the PC (PC is Asus N550 16Gb RAM and i7 4700 CPU)

I bought a brand new SSD disk, and I installed (fresh) Windows 8.1 Pro 64-bit (The OS is genuine and activated)

Then I faced a very annoying issue. The SDK8.0 installation always return an error which is difficult to understand

Cannot post a screen capture since I just created my account on stackoverflow The error popup says Setup Failed Install cannot continue because some required components failed Please correct the following problem and restart the setup...

And here is the extracted portion from the installation LOG file

I tried to install the big iso file or the small installation file (SDK8.0). Exactly same issue.

Funny enough the same iso file installation was running successfull on the same PC (running windows 8.0 instead of windows 8.1 pro)

Any help would be appreciated

Try this; MSDN Link

It seems that some certificates on Microsofts end are expired.

Edit; in short; Set your system date back to September 1st 2013 or earlier.
