I've had bad results with the RST drivers. I had to manually remove them (even 11.7) because it was causing my Windows 7 64 bit machine to freeze (or generate a stop if I was lucky). All I got from support was to reinstall Windows (because it's software problem).
I had to manually remove the drivers in a complicated manner which I thought was a big pain, since removing the drivers via the Windows Management Console only pretended to remove the low level file filter iastora.sys and iastorf.sys from being loaded for the drives.
So you can install 11.7 from the download page, but I would then test your system for at least 2 days of file transfers between devices before you go on from it.
Or don't and trust Intel to release drivers that just work (I did, and that was not the brightest choice).
