The 3rd link in my signature covers pretty much all there is to know about rsd lite, and that thread covers a lot of issues folks have had.
The part of putting it on the root of the C drive is in there, but that was a solution that worked for folks who selected the SBF file and the start button remained grayed out. Coincidence or not, putting the SBF file on the root of their C drive made the start button selectable for them. Just let RSD Lite install where it wants to.
You did install the drivers though, right? You can't install the wrong ones, but do have to install the right ones
RSD installed, drivers installed, SBF file downloaded and selected, start button goes. Fail. Sometimes it says it failed when it really didn't. Some posters do this 3-4 times, then reboot to see if SPRecovery is installed or not. Some give up and move onto another computer and it works fine there. A low battery probably wouldn't give an error but I would never flash a rom without having at least 80% battery charged, just to be safe. Many have gotten stuck in bootloops and panicked until their phone was on the charger long enough to fully boot up again.
