Some players using **Bitdefender** may experience an issue where HorizonXI appears to start, but immediately closes before the game window appears. The typical symptom is:
'''The bootloader window opens briefly and immediately closes when using Bitdefender.'''
 
After clicking **Play HorizonXI** and then **Launch**, a command prompt/console window flashes briefly for about one second, then disappears. The HorizonXI Launcher may also close afterward, and no game window opens.


This can happen even if HorizonXI has been reinstalled, installed to a different drive, run as administrator, or if legacy Windows components such as DirectPlay have already been enabled. In this case, the issue may be caused by **Bitdefender Advanced Threat Defense** blocking HorizonXI’s boot process.
If you are using '''Bitdefender''' and pressing '''Play HorizonXI''' / '''Launch''' causes a command prompt or console window to flash briefly before closing, Bitdefender Advanced Threat Defense may be blocking HorizonXI's boot process. The HorizonXI Launcher itself may appear to work normally, but the game will not open because Bitdefender is blocking one of the underlying boot executables.


The important detail is that simply disabling Bitdefender may not resolve the issue. Instead, you need to add **Advanced Threat Defense exceptions** for the actual HorizonXI boot executables, not just the launcher.

Make sure you are adding exceptions for **ashita-cli.exe** and **horizon-loader.exe**, not only for the HorizonXI Launcher itself. The launcher may start normally, but Bitdefender can still block the underlying Ashita/bootloader process that actually starts the game.
 
After adding these exceptions, restart the launcher and try launching the game again.


In short: if the launcher opens, a console window flashes, and then everything closes with no visible error, and you are using Bitdefender, check **Advanced Threat Defense** first. This issue can persist even if Bitdefender appears disabled, so proper executable exceptions are required.
Make sure you are adding exceptions for <code>ashita-cli.exe</code> and <code>horizon-loader.exe</code>, not only for the HorizonXI Launcher. After adding these exceptions, restart the launcher and try launching the game again.

Bitdefender Advanced Threat Defense Blocking HorizonXI Launch

Here is a new section I propose adding under "Bootloader Problems,".

Bitdefender Advanced Threat Defense Blocking HorizonXI Launch

The bootloader window opens briefly and immediately closes when using Bitdefender.

If you are using Bitdefender and pressing Play HorizonXI / Launch causes a command prompt or console window to flash briefly before closing, Bitdefender Advanced Threat Defense may be blocking HorizonXI's boot process. The HorizonXI Launcher itself may appear to work normally, but the game will not open because Bitdefender is blocking one of the underlying boot executables.

This can happen even if HorizonXI has been reinstalled, installed to a different drive, run as administrator, or if legacy Windows components such as DirectPlay have already been enabled. Simply disabling Bitdefender may also not resolve the issue.

To fix this, add Advanced Threat Defense exceptions in Bitdefender for the actual HorizonXI boot executables, not just the launcher:

  • ashita-cli.exe
  • horizon-loader.exe

The horizon-loader.exe file is usually located inside your HorizonXI installation folder under:

Game\bootloader\horizon-loader.exe

Make sure you are adding exceptions for ashita-cli.exe and horizon-loader.exe, not only for the HorizonXI Launcher. After adding these exceptions, restart the launcher and try launching the game again.
