libusb loading problem

Bruce Rushton
I am working on an AVR project and the AVR programmer (AVRDUDE) cannot find "device USB".  I  was told that libusb-Win32 was needed to solve the problem.  I am running a dual core 2.0 GHz 32 GB 64-bit Windows 7 laptop.  When I try  "install-filter-win" in the "bin" file, I get the Windows message that
 
 "The version of this file is not compatible with the version of Windows you;re running.  Check your computer's system information to see whether you need an x86(32-bit) or x64(64-bit) version of the program, and contact the software publisher"
 
Can you offer a solution?

Which install-filter-win.exe do you use? For 64bit Windows, if you
download the bin package, then you will need to use the 64bit
install-filter-win.exe inside bin\amd64, not the one inside bin\x86.

BTW, you also need to use the latest version of libusb-win32
which is 1.2.6.0.
http://sourceforge.net/projects/libusb-win32/files/libusb-win32-releases/1.2.6.0/

The easier way to use filter driver is to download the package
libusb-win32-devel-filter-1.2.6.0.exe and it will create the
right shortcut for you no matter you use 32bit or 64bit
Windows.
