I have attempted to install MinGW on my Win 7 system (lots of ram - a fast system). I downloaded and ran mingw-get-inst-20120426.exe. The result is that, in the All Programs menu, MinGW is listed as a directory, but within that directory, only Uninstall mingw-get is present. In C:\MinGW\ is only bin, doc, include, lib, libexc, mingw32, share, and var. There is no msys. Please advise.
