First, I assume you mean 03.2024 (or perhaps 12.2023), as 03.2026 does not exist yet.
Since the 2023 updates, Mercedes has completely removed the "Offline Mode" button and the ability to use
z / z from the standard interface. A clean installation will always force you to the Online B2B login screen.To get the offline option back, you must apply the specific раtсh for it. Since you are in the Samik FullFix thread:
- Run XENTRY FullFix By Samik as Administrator.
- Look for the checkbox or button labeled Offline Login or Common Fixes (depending on your version of the tool).
- Apply the fix.
This раtсh modifies the internal
login.html and JavaScript files to restore the offline button or bураss the login screen entirely.If you have already applied the fix and the button is still missing:
- Check your Antivirus/Defender history. It often detects the modified
login.jsorAuthenticationdlls as threats and restores the original files. - Ensure you are using a version of the FullFix that supports your specific Xentry version. Older fixers often don't work on 2024 installations because the file structure of the login page changed.
Welche FullFix Version hast du verwendet?

Falls du dich auf den Beitrag weiter oben beziehst: Der User hat geschrieben, dass er die Version 4.8.4 genutzt hat.
Generell gilt für die neueren Xentry Versionen (ab Ende 2023/Anfang 2024): Du brauchst zwingend eine neuere Version des FullFix (meistens 4.x oder höher). Die älteren Versionen finden die Pfade für den Login-раtсh nicht mehr, da Mercedes die Struktur der
login.html und der Java-Dienste geändert hat.

This usually happens if a background service fails to start or a patched file was blocked by the system.
Please check the following points:
- Secure Boot: Go into your BIOS and make sure Secure Boot is Disabled. The раtсh uses modified DLLs that often fail to load if Secure Boot is active.
- Antivirus: Check Windows Defender or your AV history. It likely quarantined a file in
(usually a DLL related to authentication or the diag service).Code:
C:\Program Files (x86)\Mercedes-Benz\Xentry\bin - Services: Open
and check if the Xentry Diagnosis Service is running. If it is stopped, try to start it manually.Code:
services.msc
If it still hangs, try re-applying the FullFix as Administrator, but make sure your antivirus is disabled during the process.

If the service is completely missing from the list, your base installation is likely corrupted or incomplete. This often happens if the setup was interrupted or if Windows Defender deleted the service executable immediately during installation.
- First, check if the file actually exists on your disk:
(The path might vary slightly depending on your version, but look in theCode:C:\Program Files (x86)\Mercedes-Benz\Xentry\bin\XentryDiagnosisService.exebinfolder).
- If the file is missing: You must reinstall Xentry. There is no fix other than replacing the missing files or running the setup again.
- If the file is there but not in services: You can try to register it manually. Open Command Prompt (CMD) as Administrator and run:
Code:sc create XentryDiagnosisService binPath= "C:\Program Files (x86)\Mercedes-Benz\Xentry\bin\XentryDiagnosisService.exe"
However, if the service is missing, usually other registry keys are missing too. I strongly recommend a clean reinstall with your Antivirus disabled.

You're welcome!
I'm glad I could help. If you manage to get it working after the reinstall, please let us know. It helps others to confirm that the clean reinstall solved the missing service issue.
Good luck!
