[求助] C++调用NIST物性出错。。。求大神分析

这是NIST9.0里面Examples文件夹里面自带的c++调用物性的例子，但是编译之后就出错。。。小弟不才，求大神分析分析，什么原因？？谢谢！！
源代码：
#include <windows.h>
#include <stdio.h>
#include "C:\Program Files\REFPROP\Examples\refprop1.h"
const long refpropcharlength=255;
const long filepathlength=255;
const long lengthofreference=3;
const long errormessagelength=255;
const long ncmax=20;
const long numparams=72;
const long maxcoefs=50;

void main(int argc, char* argv[])
{
HINSTANCE RefpropdllInstance;
RefpropdllInstance = LoadLibrary("C:\program Files\refprop\refprop.dll"

;

   long i,ierr;
   char hf[refpropcharlength*ncmax], hrf[lengthofreference+1],
   herr[errormessagelength+1],hfmix[refpropcharlength+1];

   char *FLD_PATH;
   FLD_PATH = "C:\\Program Files\\REFPROP\\fluids\\";
   strcpy(hf,FLD_PATH);
   strcpy(hfmix,FLD_PATH);

   i=1;
   strcpy(hf,"co2.fld"

;
strcpy(hfmix,"hmx.bnc"

;
strcpy(hrf,"DEF"

;
strcpy(herr,"Ok"

;

   SETUPdll(i, hf, hfmix, hrf, ierr, herr,
   refpropcharlength*ncmax,refpropcharlength,
   lengthofreference,errormessagelength);
   if (ierr != 0) printf("%s\n",herr);

double wm,ttp,tnbp,tc,pc,dc,zc,acf,dip,rgas;
long info_index=1;
INFOdll(info_index,wm,ttp,tnbp,tc,pc,dc,zc,acf,dip,rgas); //调用工质基本属性
printf("WM,ACF,DIP,TTP,TNBP %10.4f,%10.4f,%10.4f,%10.4f,%10.4\n",wm,acf,dip,ttp,tnbp);
printf("TC,PC,DC,RGAS       %10.4f,%10.4f,%10.4f,%10.4f,%10.4f\n",tc,pc,dc,rgas);
}

编译后出错：
Loaded 'ntdll.dll', no matching symbolic information found.
Loaded 'C:\Windows\SysWOW64\kernel32.dll', no matching symbolic information found.
Loaded 'C:\Windows\SysWOW64\KernelBase.dll', no matching symbolic information found.
First-chance exception in 111.exe: 0xC0000005: Access Violation.
弹出对话框：

求问大神，这是哪里有问题？？这是软件自带的例子啊！！！谢谢了
