To those with "unsigned driver" issues. or trying to use X86 drivers on X64.
May I suggest that you google "using unsigned drivers windows (insert your flavour here)"
If windows balks at X86 drivers on an X64 system then just go get the X64 drivers and don't forget to re-boot after installation.
Or again google "using x86 drivers on x64"
