Installing a driver via pnputil

Question

I'm trying to install an .inf file via NSIS like (Installing a driver in NSIS script).

Installation itself works smooth, but Windows installs the driver with its internal published name (an incrementing number oemxxx.inf).

How can I get pnputil.exe to give me the published name as return value (for later usage)?

Answer 1

What I did to get the published drivername in nsis is this hell of a workaround:

1. put the list of installed drivers to a text-file via pnputil /e > driverlist_before.txt
2. install new driver via pnputil /i /a mydriver.inf
3. put the list of installed drivers to a text-file via pnputil /e > driverlist_after.txt
4. put following code in a .cmd file and execute it via nsExec

content of GetPublishedDrivername.cmd

@echo off
:: look at differences between files and just keep the line with the oem info
fc mydriverlist_before.txt mydriverlist_after.txt | findstr /C:"oem" > diff.txt
:: cut result and keep second part               "           oem##.inf"
for /f "tokens1,2 delims=:" %%a in (diff.txt) do (
  if "%%a"=="Published name " set info=%%b
)
:: get rid of leading spaces                     "oem##.inf"
for /f "tokens=* delims= " %%a in ("%info%") do set info=%%a
:: split "oem##.inf" and keep first part         "oem##"
for /f "tokens=1,2 delims=." %%a in ("%info%") do set info=%%a 
:: get of the oem part                           "##"
set info=%info:oem=%
:: convert string into int value
set /a info=%info%
del diff.txt
:: return number as result
exit /b %info%

This script can surely be optimized, every input is welcome.

I think that is not possible. Here is a list of all commands of PnPUtil:

Microsoft PnP Utility

Usage:

pnputil.exe [-f | -i] [ -? | -a | -d | -e ]

Examples:

pnputil.exe -a a:\usbcam\USBCAM.INF -> Add package specified by USBCAM.INF

pnputil.exe -a c:\drivers*.inf -> Add all packages in c:\drivers\

pnputil.exe -i -a a:\usbcam\USBCAM.INF -> Add and install driver package

pnputil.exe -e -> Enumerate all 3rd party packages

pnputil.exe -d oem0.inf -> Delete package oem0.inf

pnputil.exe -f -d oem0.inf -> Force delete package oem0.inf

pnputil.exe -? -> This usage screen

So you cannot extract that information and pass it to NSIS easily :(
