    ACPI driver


    I installed windows 8 dev privew on my netbook (Asus EEEPC 1001PX)
    After installing keyboard filter and hotkey service in order to use Fn hotkeys(both from Asus), an error message that sayid "missing ACPI driver" kept popping out evertytime a key was pressed. So I tried installing the latest version of ACPI driver from Asus's website hoping it would fix the problem. However during the last step of installation, it would fail and rollback the installation. I have also tried a few different versions of the driver as well as running them under compatibility mode. Unfortunately none of them worked. Any suggestion?

    Try replacing the drivers with \Windows\System32\DriverStore\FileRepository\ACPI two files acpi.sys and acpi.inf

    Try running as administator and/or compataility mode
    Compatibility Mode - Windows 7 Forums

    If you can, try extracting the .inf and .sys with 7zip and installing them manually.

    i have the same problem with my eee 1215B from Asus. I uninstalled the driver, but cant use my hotkeys anymore. Contacted Microsoft but it's Asus that needs to update their drivers for win8

    what do you mean with "Try replacing the drivers with \Windows\System32\DriverStore\FileRepository\ACPI two files acpi.sys and acpi.inf " Replace by which drivers?
