I remember installing Emulate, Logix, Linx and others a few months ago on my new Win7 machine, and I thought I tested everything, and maybe I did. I was able to figure out what I needed using alternate methods. It's not a deal breaker, just something I noticed today when I was trying to analyze some code from a machine that was unavailable for real testing.
That may be the case, but I have slept since then The first time time I installed Emulate 500 in '06 on my old XP box, and the recent time a couple of months ago, I don't recall the 'EMU' driver being a separate installation or optional within the RSLinx/Emulate installation. It is not available in the drop down list when I configure drivers. I did not install it outside of the normal installation of Emulate 500 and RSLinx. Is the driver NOT available in Linx OR did you not install it?
