Just to let everyone know. You can find the knockoff hardware much cheaper other places. The software can be downloaded from the PA Soft website. Great tool to help diag many problems, view, clear, and read codes and airbag lights. I have the exact same thing for my e46 running on windows Vista 64bit. There is a very comprehensive thread over on bimmer formus about this. If you diy your own car this is a GREAT tool to have.
