I just bought the smpk8854b and had the initial problems reported by everyone else. Use the installation disk, but allow it to open instead of using the "start" menu and "run" option. When the disk opens, there are four different "programs" on this little disk. Open each one separately! Follow the instructions to the letter. I know how small the writing is. I found a magnifying glass and read the instructions...to the letter! It works very well.
