GetLastError() return value 2

Question

A very basic question, I cannot understand why I get error 2 with the simplest example of windows system programming book. I post the source:

#include <Windows.h>
#include <stdio.h>
#define BUF_SIZE 65536

int main(int argc, LPTSTR argv[]){

HANDLE fileIN, fileOUT;
DWORD nIn, nOut;        //numero di byte LETTI/SCRITTI
CHAR buffer[BUF_SIZE];

if(argc!=3){
    printf("Usage: %s file1 file2\n", argv[0]);
    return 1;
}
//printf("%s\n",argv[0]);
//printf("%s\n",argv[1]);
//printf("%s\n",argv[2]);

fileIN = CreateFileW(argv[1],GENERIC_READ,FILE_SHARE_READ,NULL, OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);
if(fileIN == INVALID_HANDLE_VALUE){
    printf("Invalid handle value, error %x\n", GetLastError());
    return 2;
}
fileOUT = CreateFileW(argv[2], GENERIC_WRITE,0, NULL, CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL, NULL);
if(fileOUT == INVALID_HANDLE_VALUE){
    printf("Invalid handle value, error %x\n", GetLastError());
    return 3;
}

while(ReadFile(fileIN, buffer, BUF_SIZE, &nIn, NULL) && nIn > 0){
    WriteFile(fileOUT, buffer, nIn, &nOut, NULL);
    if(nIn != nOut){
        printf("During copy, error %x\n", GetLastError());
    return 4;
    }
}
CloseHandle(fileIN);
CloseHandle(fileOUT);
return 0;
}

Can you help me please? I'm using MS VSc++ 2010 SP 1 Thank you all in advange N.

Please, forgive me if I am wrong but I believe that you are trying to create files with functions unicode and, may be, you are providing paths ansi. It is easy to test if I am wrong changing the terminating W into A. Please, forgive my possible error.
