Autodata: Runtime Error 217 At 00580d29

Compile with cl /LD /GS- crash.cpp — load DLL in target process → triggers error 217 at that address. Many AutoData versions store config in %APPDATA%\AutoData or C:\ProgramData\AutoData . Delete or corrupt these files, then launch:

BOOL APIENTRY DllMain(HMODULE, DWORD reason, LPVOID) { if (reason == DLL_PROCESS_ATTACH) CrashAt00580d29(); return TRUE; }

@echo off del /f /q "%APPDATA%\AutoData\*.dat" 2>nul del /f /q "%PROGRAMDATA%\AutoData\*.cfg" 2>nul reg delete "HKCU\Software\AutoData" /f 2>nul start autodata.exe Force DEP on for the executable (even if not DEP-aware): autodata runtime error 217 at 00580d29

program SimulateError217; {$APPTYPE CONSOLE}

procedure TFakeObject.CrashMe; begin Writeln('This will not be reached'); end; Compile with cl /LD /GS- crash

type PFakeObject = ^TFakeObject; TFakeObject = class procedure CrashMe; virtual; end;

Compile in and run on Windows → triggers 217. 2. Inject exact address 00580d29 crash If you need to reproduce the exact address, create a DLL or executable with a procedure at that relative offset: corrupt VMT -&gt

// Call virtual method -> corrupt VMT -> runtime error 217 obj.CrashMe; end.
