64 bit version
Dec 9, 2009 V1.0 of this readme - initial release.  Interface firmware version 1.8



The following 4 files are required for the driver installation for the CAN-4-USB/FX model
(if you are using an older, non FX interface, these drivers will not work.  Non FX models 
are not supported under Vista and Win7)

C4UFXScript.spt
can4usbfx64.cat
zanusb64.sys
CAN4USBFX64.inf

Instructions:  There are a number of versions of Windows and each one installs differently
so without going into too much detail (ie, contact Zanthic if you get stuck) the basic 
idea is that Windows is going to want to search your computer and the Internet for the 
latest drivers...you don't want that.  Save the 4 files shown to somewhere on your computer
and then when you plug the interface in, stop the install process (if it is trying to search
on its own), open the Device Manager, select the interface from the list (it may show 
up as an unknown device at this point) and tell it that you will manually select the 
files (you may have to "Update Drivers").  Point to the directory that you saved
the 4 files and all should install properly.  These are code signed drivers that will ask
you if you want to trust software from Zanthic Technologies Inc., say Yes to that part!

The interface will install as two different devices, the first being the firmware loader and
the second being the actual running interface.  When you are complete, your Device Manager
should show the "Zanthic CAN-4-USB/FX" device with no warning signs.  Also, when the firmware
is successfully loaded into the interface, the LED on the interface will switch from red to green.

If you double click on the entry (in Device Manager) you will see that the driver provider
is Zanthic and that it is digitally signed.  If you look at the driver details, you will note
that the zanusb64.sys file is being used but that the provider is Cypress Semiconductor and 
that it is not signed.  This is normal. 


NOTE1:  With the change to this version of the driver (As of Nov 2009) the support file ZCAN4USBFX.DLL
has also changed!  If you are using the Zanthic supplied test program or if you have written 
your own programs that access the ZCAN4USBFX.DLL file, you need to delete any old version of this
file on your machine and replace them with the new DLL included in this zip.  All your software
will work the same and all the function calls are identical, but, there was a change made that
required the new DLL to be used.

NOTE2: If your software was working and you've installed the new drivers and now your software says
that no interface is found, even though the interface is plugged in and working...go back and
re-read NOTE1.  If you are using the new drivers with the old ZCAN4USBFX.DLL, it will report that
the interface is not found.  Find the old ZCAN4USBFX.DLL files (pre Nov 2009) and delete them

NOTE3: If you have written a custom DLL based on the libraries that we have provided, you will have
to make some minor changes to your files and recompile your DLL's.  See the notes in the seperate
readme located on the Zanthic web site where you downloaded the drivers from.  Your old DLL will
respond in the same way, reporting that there are no interfaces present until you re-compile with
the changes.
