Exe not working properly outside of visual studio?

My program runs fine in the IDE (Visual Studio 2022), in debug and release modes.

When I make a build and want to start the .exe from Explorer, it starts and runs, but... well, have a look:

This is how it should be:

IDE output

This is what it looks like outside of VS:

EXE output

So far, I have tried to set the Runtime Library to Multi-threaded (/MT), but that didn't work.

Otherwise, I really don't seem to find much. It seems the standalone .exe is missing some dependencies, but I can't figure out what I need to do. From my understanding, everything I have included in the header should get compiled "into" the .exe as well.

The int128_t doesn't seem to work. Neither do the ANSI color codes. The timer is working, though.

The code:

#include <iostream>
#include <chrono>
#include <boost/multiprecision/cpp_int.hpp>

namespace mp = boost::multiprecision;

bool isPrime(mp::int128_t n);
mp::int128_t n{ 0 }, y{ 0 };

int main()
{
    std::cin >> y;
    std::cin >> n;
    std::cout << "\n";
    
    for (y; y <= n; y++)
    {
        int lengthy = to_string(y).length();

        const auto start = std::chrono::steady_clock::now();

        if (isPrime(y) == true)
            std::cout << "\033[1;7;32m" << std::setw(lengthy) << std::left << y << "\033[0m ";
        else
        {
            std::cout << std::setw(lengthy) << std::left << y << " ";
        }

        const auto end = std::chrono::steady_clock::now();
        std::chrono::duration<double> elapsed = end - start;

        if (elapsed.count() >= 0.1)
            std::cout << "\033[1;7;36m" << std::setw(10) << std::left << elapsed.count() << "\033[0m ";
        else
        {
            std::cout << "\033[1;36m" << std::setw(10) << std::left << elapsed.count() << "\033[0m ";
        }
    } 

    std::cout << "\n";
    std::cin >> y;
}

bool isPrime(mp::int128_t n)
{
    if (n == 2 || n == 3)
        return true;
    
    if (n <= 1 or n % 2 == 0 or n % 3 == 0)
        return false;
    
    for (uint64_t i = 5; i * i <= n; i += 6)
    {
        if (n % i == 0 or n % (i + 2) == 0)
            return false;
    }

    return true;
}

Windows terminal supports ANSI escape sequences but not in default. You have to set up in some cases. This is the solution:

Windows Start --> run regedit --> add new variable to HKEY_CURRENT_USER/Console (name: VirtualTerminalLevel type: double word value type: decimal value: 1)

I've been able to enable Color Codes in default Windows terminal using the following code:

#ifdef _WIN32

#include <Windows.h>

void enableColors()
{
    DWORD consoleMode;
    HANDLE outputHandle = GetStdHandle(STD_OUTPUT_HANDLE);
    if (GetConsoleMode(outputHandle, &consoleMode))
    {
        SetConsoleMode(outputHandle, consoleMode | ENABLE_VIRTUAL_TERMINAL_PROCESSING);
    }
}

#endif

Call it once at the start of the main function.

See https://en.wikipedia.org/wiki/ANSI_escape_code, specifically:

In 2016, Microsoft released the Windows 10 version 1511 update which unexpectedly implemented support for ANSI escape sequences, over two decades after the debut of Windows NT.[13] This was done alongside Windows Subsystem for Linux, allowing Unix-like terminal-based software to use the sequences in Windows Console. Unfortunately this defaults to off, but Windows PowerShell 5.1 enabled it. PowerShell 6 made it possible to embed the necessary ESC character into a string with `e.[14] Windows Terminal, introduced in 2019, supports the sequences by default, and Microsoft intends to replace the Windows Console with Windows Terminal.[15]

Color codes work in Visual Studio Code (Terminal).
