well, after god know's how many attempts, it is finally installed
what i overlooked was the size of GWX 6 bin file. compared it with all the other download sites and found the size well out. downloaded another, uninstalled, reinstalled, ran the patch not knowing that it successfully done then again clicked the GWX exe!!!!
and eu "bloody" reka!!!!, its done!!!!!!
bugger work, i'm catching up for lost time
again, thanks.......
