OK I tried for an hour to make it work, and I kept getting usb error 170.... I found the fix and it was simple.... When the RUU loads it loads BOOTLOADER driver, when the phone restarts it's self (to the white load screen) the phone driver is switched from the "my HTC" driver to the new BOOTLOADER driver. It doesn't like that... and errors. then you open device manger, and right click on bootloader and choose update driver software. then choose brows my computer..... now click on the bottom link, "let me pick from the device list, If i remember right there was 2 options (something) and HTC. Click the htc and choose the "my HTC driver. Restart the RUU. 10 Mins later you are done. I have done it twice. Good Luck!
