INSTALL-------Place these files in some directory (Avoid pathnames containing white spaces or non-ascii characters).Disk space of 200MB or so is required.1) Execute install-mingw.bat.   MinGW and MSYS are installed under current directory.   Sub directories such as bin, include, lib,... are created.2) Execute build_libfdk_aac.bat.3) Execute build_fdkaac.bat.Finally, you will get fdkaac.exe in the current directory.You can place it to anyware you want.If you only need fdkaac.exe and don't need to update it,you can safely remove other files/directories.Special uninstallation is not required.Otherwise, you might want to keep MinGW/MSYS.In this case, you can skip step 1 on the next time.If you want to move/rename this directory, you have to execute fstab-fix.bat,so that will point MinGW/MSYS to the new directory.If step 1 fails for some reason, you can still manually download mingw-get-*-bin.zip from http://sourceforge.net/projects/mingw/files/Installer/mingw-get/, place the donloaded file here, and try running install-mingw.bat again like this:C:\foo\bar> install-mingw.bat mingw-get-0.6.2-mingw32-beta-20131004-1-bin.zip (You have to pass the actual filename of mingw-get-*-bin.zip)
