--- Comment #2 from xantares  ---
I think it could come from dlls/ntdll/env.c:

static void get_image_path( const char *argv0, UNICODE_STRING *path )
...
/* check for builtin path inside system directory */
        if (!is_path_prefix( system_dir, full_name, file_part ))
        {
            if (!is_win64 && !is_wow64) goto failed;
            if (!is_path_prefix( syswow64_dir, full_name, file_part )) goto
failed;
        }
...
failed:
    MESSAGE( "wine: cannot find '%s'\n", argv0 );
    RtlExitUserProcess( GetLastError() );

here it seems no error was set and GetLastError may return 0

a proposal would be to return CTL_E_FILENOTFOUND
