How to deinstall lpc device driver from the console?

palaplan — Mon, 17 Feb 2020 16:02:24 GMT

Hello,

I am developping a Windows application to update Nxp Microcontrollers in DFU mode. I want the application installer to contain the necessary drivers, so that the user only needs to install my application for it to work.

During my tests I installed LPCScrypt_installer_2.1.0_842.exe and found a lpc_driver_installer.exe under C:\NXP\LPCScrypt_2.1.0_842\Drivers, when I run it the drivers are getting installed and I get the .inf files under C:\Program Files\NXP\LPC Driver Installer. There are:

lpc313x_dfu_msc
lpcdevice
lpc-linkII-hid
lpc-linkII-vcom

In my Installer I call lpc_driver_installer.exe from the console in silent mode and it works well, but I also need to be able to deinstall the drivers. When I call the help page of lpc_driver_installer.exe I can see this:

Windows ® Installer. V 5.0.18362.1
Installationsoptionen
 ...
 </uninstall | /x> <Produkt.msi | Produktcode>
  Deinstalliert das Produkt.‍‍‍‍‍

I tried to call lpc_driver_installer.exe /uninstall, but the problem is that I am not able to find the corresponding Product code. I ran this Installer with the log option and found this:

...
Property(S): Manufacturer = NXP
Property(S): MsiLogging = v
Property(S): NewDirIcon = New
Property(S): PROMPTROLLBACKCOST = P
Property(S): ProductCode = {18BC6831-5259-4914-B09A-DE370BCF8AD1}
Property(S): ProductLanguage = 1033
Property(S): ProductName = LPC Driver Installer
Property(S): ProductVersion = 2.0.2
Property(S): Progress1 = Installing
Property(S): Progress2 = installs
...‍‍‍‍‍‍‍‍‍‍‍‍

I tried to call lpc_driver_installer.exe /uninstall {18BC6831-5259-4914-B09A-DE370BCF8AD1} but got an error window "Patch was not applied to this product" (translated from german).

Can someone tell me where to find the correct product code or if I am doing something wrong?

Many thanks,

Pierre

You could use the command line utility

pnputil

This allows you to enumerate devices and to delete them (as well as install them etc).

try

pnputil /help

For information

Hello and thank you for the quick answer,

I tried your method with pnputil and it works fine, I can get the list of all installed Drivers with pnputil /enum-drivers:

C:\Users\Tester\Desktop\tmp>pnputil /enum-drivers
Microsoft-PnP-Hilfsprogramm

Veröffentlichter Name:     oem6.inf
Originalname:      lpc-linkii-hid.inf
Anbietername:      NXP
Klassenname:         Eingabegeräte (Human Interface Devices)
Klassen-GUID:         {745a17a0-74d3-11d0-b6fe-00a0c90f57da}
Treiberversion:     11/03/2014 1.0.0.1
Name des Signaturgebers:        NXP Semiconductors USA. Inc.
...‍‍‍‍‍‍‍‍‍‍‍

then I can deinstall a driver with pnputil /delete-driver oem#.inf

C:\Users\Tester\Desktop\tmp>pnputil /delete-driver oem6.inf
Microsoft-PnP-Hilfsprogramm

Das Treiberpaket wurde erfolgreich gelöscht.‍‍‍‍

The problem for me is that in that case I would be forced to parse the Standard Output and find the correct oem#.inf file, which also sounds risky!

Another method I thought About is with dpinst, included in DIFX, which was part of the Windows Driver Kit (WDK). There is a 32 bits and a 64 bits Version of the tool, and for it to work you need the .inf files with the corresponding .cat files, which I got from the LPCScrypt Installation.

I found out, that there are 2 different help pages for lpc_driver_installer.exe, one with

lpc_driver_installer.exe /h‍

which seem to give a list of msiexec Parameters, and another one with

lpc_driver_installer.exe /?‍

which gives a list of setup parameters, like /extract for example.

I managed to extract the setup in a local directory and found out that it contains:

lpc_driver_installer.msi
lpc_driver_installer.x64.msi
and directories lpc313x_dfu_msc, lpcdevice, lpc-linkII-hid and lpc-linkII-vcom containing the .inf files

Installation:

msiexec /i lpc_driver_installer.x64.msi‍

did not work, I get an error "This package can only be run from a bootstrapper". So I still have to use lpc_driver_installer.exe, but once the programm is installed I can deinstall it with the .msi file.

Deinstallation:

msiexec /x lpc_driver_installer.x64.msi‍‍‍‍

or in quiet mode

msiexec /q /x lpc_driver_installer.x64.msi‍

So this is an acceptable solution, though I am a bit upset, that I have to use a combination of setup AND msi to install/deinstall the drivers but the result looks clean.

In case you need it for future reference, this link gives a simple way to parse the pnputil output
