title: Installing Cargo on Windows with Rust from MSYS2
body: <p>I've installed Rust on my Windows 7 64-bit system via MSYS2 successfully, but when trying to install Cargo from nightly build, I get the following error from <code>install.sh</code>:</p>
  
  <pre><code>$ ./install.sh
  install: looking for install programs
  install:
  install: found mkdir
  install: found printf
  install: found cut
  install: found grep
  install: found uname
  install: found tr
  install: found sed
  install:
  install: processing ./install.sh args
  install:
  install: CFG_DESTDIR          :=
  install: CFG_PREFIX           := /usr/local
  install: CFG_LIBDIR           := /usr/local/lib
  install: CFG_MANDIR           := /usr/local/share/man
  install:
  install: validating ./install.sh args
  install:
  install: verifying platform can run binaries
  install: error: can't execute rustc binary on this platform
  </code></pre>
  
  <p>While <code>rustc</code> works just fine:</p>
  
  <pre><code>$ rustc --version
  rustc 0.13.0-nightly (5ba610265 2014-12-25 18:01:36 +0000)
  </code></pre>
  
  <p>Am I doing something wrong?</p>
