A call to an OS function failed in Win64 build using InstallHook

I have a simple InstallHook that perform nothing:

```pascal
function MyHook(lpLibFileName: PWideChar): Pointer;
begin
  Result := nil;
end;

initialization
  InstallHook(MyHook);
finalization
  UninstallHook;
end.
```
When launch the application build with Win64 platform, it raise `A call to an OS function failed` error.

The above code works on Win32 build.
