Being sure to specify the location of the drivers, of course. They also told me that the drivers were installed in two stages: (a) the firmware, and (b) the USB driver. I don't think that I had picked up on this before. That "preinstall utility" really sucks! Mine seems to work OK now, to the extent that I no longer get error messages about "new hardware" when I plug it in the USB port. But have not actually tried it out yet, so cannot guarantee it works. I think that I have the code for an 18F452 routine that I wrote around here somewhere, so will use that and see if I can program it using the ICD2. If it does not work then I will contact Microchip again. They are very nice, and very helpful. So far as "the blue screen of death" I have not had that problem.
