okay, first thing you need to do to install vcom drivers is to disable the mandatory digital signature enforcement in windows 8.
(Yeah this is a stupid thing msft started with windows 8, the VCOM drivers are not digitally signed so windows won't install even if you have admin rights.)
Step 1. Go to the right bottom corner of the desktop and wait for the side menu to appear. When it’s there click on the gear icon with the title “Settings”.
Step 2. Now click on the entry “More PC Settings”, then click on the entry “General”.
Step 4. Scroll down to “Restart now” (under “Advanced start up ”) and click it.
Step 5. Wait a bit for a menu.
Step 6. Now click “Troubleshoot”, then “Advanced Options” and after that click “Windows Start up Settings”.
Disable the digital signature enforcement and boot onto windows.
To install vcom drivers, right click the file(64bit or 32 bit) and select install.
As for the bin4ry tool, it doesn't work on jellybean for rooting. You need to install custom recovery and flash the supersu zip file.
Hope it helps.
