BDO becomes "Not Responding" - xhunter1.sys missing

3 posts in this topic

Posted (edited)

Hi all,


First, my specs:


Windows 10 x64 (Anniversary update)

Intel i 4790k

12GB Ram

nVidia 980ti 6GB Gaming w/ driver version 372.70


This is a fresh install of Windows 10 with all drivers up to date. In the last 2 days I've had a couple of instances where BDO freezes/becomes Not Responding and, even if I wait a while, it never recovers and eventually I need to force close it. I have checked Event Viewer and, while I can't be certain, it seems the crashes coincide with the following entry:


The xhunter1 service failed to start due to the following error: 
Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.


At first I had no idea what xhunter1 was but a quick google suggested it was to do with the Xigncode software used by BDO. The strange thing is; I can't find xhunter1.sys anywhere on my machine. Should it be there?

Edit: ok, I just had an idea to check the installation on my laptop and the xhunter1.sys file is in my windows directory. Not sure why it has gone missing on my desktop!


Edit2: I've repaired my desktop BDO installation but the xhunter1.sys file still hasn't appeared. Is there a separate installer for the xigncode stuff?

[Window Title]
Program Compatibility Assistant

[Main Instruction]
A digitally signed driver is required



I get the above error even though I've instaleld BDO with windows in non-driver signing mode.

So, the crashes have happened again. xhunter1.sys has once more gone missing from c:/windows/ folder.


I copy the xhutner1.sys file from my laptop (latest version of BDO) and launch teh game to c:/windiws/ on my desktop. I launch the game and watch as xhunter1.sys deletes.

This is the way XIGNCODE works. After the game exits it deletes itself from disk and uninstalls the driver to ensure the driver is not loaded again when you restart your PC.

Otherwise you could sue the company as you could argue this Anticheat software is a root kit.

Maybe you should restart your PC. After restart open the console and execute: driverquery /v

xhunter1.sys should NOT be included here. If it is still included then there went something wrong during uninstallation and you have to remove the xhunter driver manually before you start the game again.
