Silent installation for 2 drivers

[coucou]

Hello,

I've already prepared my unattended win7 with DriverPacks integrated (DP_Audio; DP_Chipste; DP_CardReaders; DP_Graphics_A, B and Mobile; DP_LAN; DP_WLAN; DP_MassStorage).

I also added some software to be installed silently. So, Win7 is installed like a charm. On the other hand, the software installation is looking for 2 drivers pcouffin.sys and ezplay.sys.

Actually I've the .exe files of these drivers (PCouffinSetup.exe and EzPlay.exe).

1) How do I extract the drivers from the .exe files ?

2) How to install them silently with NO reboot?

I'll appreciate any help

Regards
