Default [Q] Unable to root C6502 Ver 4.3 Build 10.4.B.0.569

Hello Expert,

I'm having trouble rooting my C6502 Ver 4.3 Build 10.4.B.0.569 but just to make sure of things, i've also re-imaged my laptop just to make sure that it isn't my laptop that's causing this.

I'm using DoomLoRD Rooting Kit v18 and I've also installed the ADB driver as per advised in previous threads
Driver obtained from h t t p : / / developer. sonymobile. com/ downloads/ drivers/ xperia-z-driver/

On my device, I've enabled the following;
Developer Options > USB Debugging - Checked
Security > Unknown Sources - Checked

Device is connected via USB cable and launched "runme_win" via administrator, just to make sure.
And the process stops at the following step (please refer attachment) and nothing happens after that

This working well with my Xperia J (ST26i) and i don't know what am i doing wrong here
Please advice
