title: MinGW-w64 offline installer
body: <p>is there any way to install mingw-w64 offline ? I tried many official sources and all of them seem to need some sort of internet access. I'm looking for something that works for both x32 and x64 systems. I tried to have a look at <a href="https://sourceforge.net/p/mingw-w64/mingw-w64/ci/master/tree/" rel="noreferrer">the official repository</a> but I am not sure which files I need for this task.</p>
  
  <p>Thanks in advance !</p>
