I want to use DFUSec.exe tool to program internal flash using DFU.
My problem is I am unable to install WinUSB driver for my Keil NXP LPC4357 Evaluation board.
I am using MS Win7.

I followed this topic http://www.lpcware.com/content/project/dfu-download-programming-utility-and-security-lpcdfusec-tool/winusb-driver-installat
which suggest to "Un-compress the drivers and point the driver installation dialog to the INF file in the uncompressed package." but I can't find the INF file anywhere.

There is unrecognised "LPC" device in Device Manager despite trying to install the LPC-Link 2 Configuration Tool
based on http://www.lpcware.com/lpclink2-config-tool
and to install LPCXpresso Link2 USB driver package
based on http://www.lpcware.com/content/nxpfile/lpcxpresso-link2-usb-driver-package

Any suggestion? Thank you!

This file no longer exists standalone as part of the original procedure. It's installed as part of the v2 LCT or driver packages.
I've updated the page to indicate you only need to download and install the driver package.

Did the installer work without any issues? If you are sure the installer worked ok, check to make sure the following directories have been created:
C:\Program Files\NXP\LPC Driver Installer <<<< Drivers
C:\Program Files\NXP\LPC-Link 2 Configuration Tool << LCT/DFUSec tool

If things don't seem to work, uninstall the packages listed above and run the installer from the command line with the options below and post the log here.
"lct_installer.exe" /L*V "install.log"

Note: The v2.02 update is coming soon for the LCT. The v2.01 LCT will not install if later versions of the LPC Driver package are already installled. If you have have installed the v2.02 LPC Driver package, you will need to uninstall that package prior to installing the v2.01 LCT. After the LCT is installed, the v2.02 driver package can optionally be reinstalled. This will be fixed in v2.02 of the LCT installer.

Yes, LCT installed without any error. Both folders installed.
LCT utility crashes immediately after start.

I was able to fix the "unrecognized device" problem by searching lpcware site and installing this lpc18xx_43xx_winusb_drivers_v1.00.zip file from this page:
http://www.lpcware.com/file_filter/nxp?term_node_tid_depth=114&term_node_tid_depth_1=104

By installing the driver manually I was able to run DFUSec.exe (ver.1.11) in Programming mode and use DFU.

I will try to run the LCT installer again and post log.

Please post or send the log so I can look at it.
In regards to the crash issue, there is a known issue list on the (http://www.lpcware.com/lpclink2-config-tool) page. You need to install NET4.5.1 to fix that issue for v2.01.
(I made that list a little more noticeable on that web page).
