The application was unable to start correctly (0xc0000005) / Exception code 0xc0000005 access violation

A program tried to read or write memory it doesn’t own and Windows stopped it — buggy software, bad drivers/plugins, security software injection or faulty RAM.

Seen on: Windows

Meaning

STATUS_ACCESS_VIOLATION. When it happens at startup, antivirus/DEP or corrupt program files are common; when many programs crash, suspect RAM or system files. The Event Viewer “Application Error” entry names the faulting module.

Common causes

  • Bug in the program or a plugin/add-in
  • Security software or overlay injecting into the process
  • Corrupt program files or runtime
  • Faulty RAM or overclock

⚡ Quick fix

  1. Check Event Viewer → Windows Logs → Application for the faulting module
  2. Reinstall/update the program and its runtimes
  3. Test without overlays/antivirus; run Memory Diagnostic
