Windows 8.1  64 bit, 16 GB

also installed :- Rosewill Dual Band Wireless N900 Adapter.

Trying to install/update LAN driver, I'm getting message 'the extended attributes are inconsistent'.

 background installation info.

installed relevant drivers via USB. ie lan driver, vga, usb, (ME didn't work/install, exe was missing on CD).

Also installed above Rosewill Dual Band Wireless Adapter.

The Network (on-board LAN 'enabled') adapter drivers did not install for some reason. The Killer LAN application was installed.

 In Windows device manager I confirmed the Network drivers were not installed. This was also confirmed running windows network diagnostics. So attempting to 'update driver' via Device manager - while trying to install the found Lan driver, I'm always getting the message 'the extended attributes are inconsistent'.

 Now, I've uninstalled Killer LAN application, re-installed a newer version. Same error message.  Tried installing drivers without Killer LAN application, same error.  I've updated the firmware to version 2.5 still no good.

 Also drivers for PCI Simple Communications Controller did not installed. 

windows device manager ??was unable to find it during ?˜update driver??/p>

The Dual Band wireless adapter drivers installed without any problems.

Pls advice.  Thx..
