battle eye wont start keeps saying its updating then starting then failed then installing again then its successful install then updating then fails and kicks me back to escape from tarkov launcher

Check whether Kernel-mode Hardware-enforced Stack Protection is blocking BattlEye’s driver; if it is enabled, temporarily turn it off, restart Windows, and launch Escape from Tarkov again.

1. Test the Windows 11 driver-protection setting

BattlEye identifies Kernel-mode Hardware-enforced Stack Protection as a possible reason its BEDaisy.sys driver cannot load. Windows confirms that some legitimate drivers are incompatible with this protection.^1^^2^

1. Open Start → Settings → Privacy & security → Windows Security → Device security.
2. Under Core isolation, select Core isolation details.
3. If Kernel-mode Hardware-enforced Stack Protection is present and enabled, turn it Off.
4. Restart the PC.
5. Open the Tarkov launcher and start the game.

Turning this feature off reduces protection against malicious or incompatible kernel drivers. Treat it as a temporary diagnostic test; if BattlEye works, obtain the latest game/BattlEye update and periodically test whether the protection can be re-enabled.

If Windows specifically reports that Memory integrity blocked a driver, first look for an updated driver. As a temporary test, Memory integrity can be turned off from the same Core isolation page, followed by a restart, but this also reduces device security.^3^

2. Use the publisher’s repair guidance

If the protection setting was already off or made no difference:

1. Work through Escape from Tarkov’s official anti-cheat troubleshooting article.^4^
2. In the Tarkov launcher, use its game integrity/repair function if available. This is preferable to repeating the automatic BattlEye reinstall loop because it checks the complete game installation.
3. Confirm that the launcher and game have finished downloading all updates before starting the game.
4. Review BattlEye’s FAQ for the exact message displayed, particularly “Failed to install BattlEye Service.”^1^

3. Isolate a background-software conflict

If BattlEye still loops, perform a clean boot:

1. Sign in with an administrator account.
2. Search for msconfig, then open System Configuration.
3. Select Services → Hide all Microsoft services → Disable all → Apply.
   Do not skip “Hide all Microsoft services.”
4. Select Startup → Open Task Manager.
5. Disable each enabled startup item, recording what you disabled.
6. Restart Windows and retry the Tarkov launcher.

A clean boot loads only essential Windows components, helping identify interference from third-party security, monitoring, overlay, or other background software.^5^

• If Tarkov works, re-enable services and startup items in halves until the conflicting program is identified.
• If it still fails, restore normal startup in msconfig → General → Normal startup, restart, and proceed to support.

4. Escalate with the exact failure details

Submit a ticket to Tarkov Support and, if necessary, BattlEye Support.^6^ Include:

• The complete BattlEye error text or error number.
• A screenshot of the update/install loop.
• Windows 11 version and system type from Settings → System → About.
• Whether Kernel-mode Stack Protection or Memory integrity was enabled.
• Whether the failure also occurred during a clean boot.

If System type says an Arm-based processor, mention that explicitly: Windows 11 on Arm requires Arm-compatible anti-cheat drivers, and games relying on unsupported anti-cheat drivers may not work.^7^
