When the program built with C::B doesn't work

I made a small c++ project and it was fully compiled and built it.

#include <iostream>

using namespace std;

int main()
{
    cout << "Hello world!" << endl;
    return 0;
}

When I run through c::b it was okay

However, it says next warnings when I run program outside of the c::b. "programdir/bin/Debug/program.exe"

So I got "libgcc_s_dw2-1.dll" from sourceforge, pasted it next to my .exe file, and I got 0xc000007b error with the error "cannot start the program"

What should I do in this case of problem?
