Xin lỗi, chưa thực hiện: 64 bit chế độ không được biên dịch trong

Question

Đây là những gì tôi đang cố gắng để làm (trên Windows 7 64-bit):

g++ -m64 -o main main.cpp 

Và lỗi tôi nhận được là:

Sorry, unimplemented: 64 bit mode not compiled in ... 

Tôi đã cài đặt mingw-64-install.exe từ đây: https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/installer/

Nhưng tôi vẫn gặp lỗi tương tự. Tôi cũng cần phải thêm đường dẫn đến thư mục này trong biến môi trường?

Cảm ơn

EDIT:

Đây là những gì tôi nhận được khi tôi gõ

g++ -v

Khi chạy mingw-64-install.exe, bạn phải chọn kiến ​​trúc x86_64 trên màn hình cài đặt. Với kiến ​​trúc này, 64-bit cũng là đích mặc định. Nếu bạn chạy g++ -v, bạn sẽ nhận được một cái gì đó như:
