Exception EAccessViolation

Question

Zugriffsverletzung bei Adresse 0000000000B38598 in Modul mhelper.exe. Lesen von Adresse 0000000000000028

Answer 1

mhelper.exe ist kein bekannter Windows-Prozess. Es liegen nur wenige Informationen zu diesem Prozess vor. Er könnte zu SearchEngineOptimizer oder einer anderen auf Ihrem PC installierten Anwendung gehören.

Wird in der Fehlermeldung angezeigt, welche Anwendung mit diesem Speichercode abstürzt?

Falls Sie die abstürzende Anwendung identifizieren können, deinstallieren Sie diese am besten, starten Sie Ihren PC neu und laden Sie anschließend die neueste Version der Anwendung herunter und installieren Sie diese.

Falls nicht, senden Sie uns bitte einen Screenshot der angezeigten Fehlermeldung.

Answer 2

The error message indicates an access violation (EAccessViolation) in the process mhelper.exe. This means that the application tried to read or write memory it is not allowed to access (here: reading from address 0000000000000028). This is a bug in the application or in a library it uses, not a normal Windows configuration issue.

Typical causes (based on similar access violation cases in Windows):

• Dereferencing an invalid or null pointer in the application code.
• Passing invalid parameters to runtime or system functions, which then terminate the process with an access violation.
• Memory corruption earlier in the process that only becomes visible when the runtime finally crashes.

To troubleshoot on Windows 10:

1. Ensure the application is up to date
   • Install the latest version or patch of the software that provides mhelper.exe.
   • If the problem started after an update, check the vendor’s release notes or support.
2. Check for known runtime issues
   • Similar crashes in other applications are often caused by bugs in the application code or in libraries, not by Windows itself. If mhelper.exe is part of third‑party software, contact that vendor with the crash details.
3. Collect a crash dump for analysis
   • Configure Windows Error Reporting or use tools like WinDbg to capture a full user‑mode dump when mhelper.exe crashes.
   • The dump allows developers (or the vendor) to see the call stack and the exact code path that led to the access violation.
4. System health checks
   • Run sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth from an elevated Command Prompt to verify system files.
   • Check Event Viewer → Windows Logs → Application for entries around the time of the crash to confirm faulting module and exception code.
5. If the executable is part of a larger product (e.g., database, security, or helper tool)
   • Follow that product’s support path. For example, in similar cases with server products (like SQL Server) or other components, the recommended path is to open a support case with the vendor or Microsoft support via the appropriate channel.

If this is a line‑of‑business or custom application, the developer will need the crash dump and symbols to debug the access violation in their code.
