I just went through this, but I am far from an expert. I had to install the drivers for the 11R to get it to work. I did it on a 32 bit windows XP system. I have the stand alone editor from avid on my laptop which is a 64bit windows 7 machine. I prefer to use the stand alone from avid. However, I think you need a 64 bit machine to run it. Again, I'm not an expert on this, but if you can't install the Avid stand alone, then the elevenhack is surely a help. HTH.
