Several days ago I lost sound on internal speakers of my laptop Asus N551JQ. Technician from the Asus Helpdesk recommended to install update of the Intel Chipset Device software (INF update) version 9.4.0.1027. I've downloaded zip file of that version from the Asus web site. However, installation failed with log: " File copying was not successful. Setup will exit" and show me CSVer.dll file. This file I found in SysWOW64 folder of my system. Inteerstingly, details show this file is from 9.4.0.1027 software version. I deleted this file from the SysWow64 and Windows update kb3126587. But it doesn't helped with the installation.
I tried several times to run setup, unsuccessfully though. I also run it from the Command line (Admin) as
setup.exe -A -S
setup.exe -OVERALL -S
After the reboot I see only readme.txt and license.txt files in the Program files (x86)/Intel/Infinst folder and 2008s4el.cat file in Program files (x86)/Intel/Infinst/Inf folder. Also, I don't see Intel/INFInst software in regedit.
I would appreciate for your suggestion how to install correctly the Intel Chipset Device Software on my PC.
