Is there an offline MinGW installer?

I did not find an offline installer for MinGW,but instead I found a better Windows port; which is MinGW-W64

From http://mingw-w64.yaxm.org/doku.php:

Mingw-w64 is an advancement of the original mingw.org project, created to support the GCC compiler on Windows systems. It has forked it in 2007 in order to provide support for 64 bits and new APIs. It has since then gained widespread use and distribution.

Now to answer this question: it has to be mannually installed by downloading the zip file. It won't require additional download.

You can download it from link : https://github.com/jonasstrandstedt/MinGW You need to extract the MinGW folder in C:\ eg: c:\MinGW . Then what you need to follow the steps given in the link above. In CodeBlock IDE go to settings>compiler>Tochain Executables. There you need to click on auto detect or specify the folder manually.
