Hi All,

I need your urgent help.

I am working in slient installation (Without Wizard) of any simple driver(PNP and non PNP drivers).

I tried to use UpdateDriverForPlugAndPlayDevices(NULL, H/w_id, inf_file, 0, &reboot) function installs updated drivers for devices

but when i call, function returns "NO_ERROR" but driver is not getting installed.Even i am nt sure whether driver installed or not.

OEMxx.inf file is nt copied at %windir%/inf location and .sys file and othe supporting files also nt copied at %windir%/system32/drivers location.

I also tried SetupCopyOEMInf(inf_file, NULL, SPOST_PATH, 0, NULL, 0, NULL, NULL) function, it copies only .inf file.

then who will copy .sys file or any other supporting driver files.

I am using below mentioned driver files :

1. hpdltw32.inf ------- Extract H/W Id from inf file

2. hpdltw32.CAT

3. hpdltw32.sys

Called UpdateDriverForPlugAndPlayDevices(NULL,H/W Id , inf_file, 0, &reboot) returns NO_ERROR

but nt copied OEMxx.inf in "%windir%/inf" pathand nt copied .sys file at "%windir%/system32/drivers".

Can any one give me driver installtion API sequence Or give me any sample code for installing sample driver.

I am waiting for your kindly help.

Even your reply or valuable suggestion would be great for me.

Thanks & Regards,

Abhijit

Put in registry device path path to drivers you want to have installed/updated and run this from command prompt: RunDll32.exe Syssetup.dll,UpdatePnpDeviceDrivers

Or use

Devcon.exe
