I also have pulled out lots of hair trying to get the drivers to function, then I had to take a step back and realize that well...I was just trying to install drivers that were NOT for a 64bit operating system lol.
Its easy to make that mistake since everyone said that it was working.
The only thing I can think is that ...most people are actually using 32bit and not 64bit, or that they just installed the drivers from the CD, which will manually select the right driver version for you.
Either way, I'm glad that I could repost this and help out.
Lots of digging, but, it was well worth it.
