How to Fix Blade and Soul Error 4049

Are you seeing something like Error 4049 when you try to launch the game Blade and Soul.? Here I’m saying about the gamers who are on the Windows OS mainly the Windows 7/8 or 10. This issue may happen due to using an older version of the game launcher. Often users try to relaunch the game while some processes of the game from the previous session are still active. This causes conflict and shows Error 4049.

Again if you have Razer hardware installed on your setup then you must check that the Razer Chroma SDK must be enabled. If you are using an updated build of the game launcher then that may conflict with the disabled SDK. This leads to Error 4049. Even not updating your GPU can cause this problem and not allow you to launch the game Blade and Soul. I have listed some detailed instructions to fix up all these issues and relaunch the game easily.

Fix Error 4049 in Blade and Soul

Let’s get started with the troubleshooting methods and how to perform them.

End the Active Game Processes

If you are planning to relaunch Blade and Soul, then it may not work. If some of the Game processes from the previous session are still active conflict will happen.

Specifically, there are three processes: BnSCefSubProcess.exe, GameMon.Des and Client.exe. If you end these processes and then relaunch the game then it will work really fine.

  • Open Task Manager by pressing Ctrl + Shift + Esc
  • Then go to the Processes tab
  • Now carefully navigate through the list of active processes running on your PC
  • Highlight the above mentioned and right-click on them individually
  • From the menu select End Task
  • Then try to relaunch Blade and Soul. I’m sure it will now load without any hiccups.

Enable Razer Chroma SDK

As I mentioned using an outdated launcher can cause conflict and show you Error 4049 on Blade and Soul. This happens when you use any Razer hardware on your gaming setup but have the Razer Chroma SDK disabled. So, to fix the error you have to re-enable the Razer Chroma SDK.
