It Seems like people are having trouble installing and activating leaked Windows 8.1 Pro Version because of the corrupted install.wim file.
I have managed to install and also activate Windows 8.1 Pro RTM.
Here is the procedure
1. Unmount using Dism as follows:
Dism /Mount-Image /ImageFile:\Sources\install.wim /index:3 /MountDir:E:\Win8\Pro
2.Capture Image:
Dism /Capture-Image /ImageFile:E:\RTM\install.wim /CaptureDir:E:\Win8\Pro /Name:"Win 8.1"
3. Create ISO:
I have used w8boot-v1. Download it from here hxxps://mega.co.nz/#!Z5JR1RJC!LhzYrnUTRuSELBcz7DvgrGFvnjN1Z-gJqu69ELi-pJg

a)Extract contents of w8boot-v1 to C:\w8boot
b)Copy install.wim created in previous step using Dism and also boot.wim from RTM frankenbuild to C:\w8boot
c)Run MakePatch.bat
It will create "en_windows_8.1_rtm_x64.iso" in C:\W8boot
d)Mount and install

4. Activation:
Use Windows 8 Pro RTM key from your MSDN.
Enjoy the activated Windows 8.1 Pro RTM.
