Thank Ekko for his original work and here is the newest driver modified by me which runs fine in Windows 8 x64. I didn't do the x32 you can do it if you wanna.

Why would I trust "Tiny DM manager (exe app) " ? Even Chrome suggests I should discard it after I download it The last thing I need is some spam toolbar installed.
