VS2013 调用openssl库出错的问题

64位win7
代码如下：

 #include<stdio.h>

 9 #define BUFFSIZE 1024
10 char* my_encrypt(char *str,char *path_key);//加密
11 char* my_decrypt(char *str,char *path_key);//解密

73     fclose(file);
74     return p_de;
75 }

调用的时候错误信息如下：

设置的include目录：

设置的lib目录：

添加的依赖项：


为什么还会出现这种错误啊？

问题出在VS编译的时候默认是32位，在配置管理器里设置成64位即可
