64-bit Windows does require signed drivers, which was not the case with the
32-bit OSes.   It works fine with both Prologix and NI hardware, but some of
the lesser-known NI clones may not have 64-bit drivers.

One nice thing about Windows 7 is that you don't have to install any drivers
at all for the Prologix hardware.   The FTDI chip in the USB adapters is
recognized right out of the box, and the Ethernet version doesn't need
specific drivers to begin with.

Unfortunately, no, it requires at least Windows 2000 (and I don't develop or
test under anything earlier than XP.)   The newest build at
www.miles.io/timelab/readme.htm does have a native 64-bit Windows version,
though. :)
