Installing MinGW RTEMS Tools

[Sam Lost]

I new to all this and I am having some problems installing the WIN32 RTEMS
Tools

I have been following the documents listed below however after two day
battling I am still stuck

http://www.rtems.org/wiki/index.php/MinGW_Tools_for_Windows#MSYS_-_Base
http://www.rtems.org/wiki/index.php/Installing_MinGW_RTEMS_Tools

I notice that the link posted for MSYS - M4 is invalid, I have googled for
it but without success.

When I run rtems4.10-tools-1.exe I receive the following error when
attempting to install rtems4.10-tools-1.exe

MinGW Not Installed. Please install MinGW from http://www.mingw.org

However

 MinGW <http://prdownloads.sf.net/mingw/MinGW-5.1.4.exe?download>
MSYS - Base <http://prdownloads.sf.net/mingw/MSYS-1.0.10.exe?download>
MSYS - Developer Tool
Kit<http://prdownloads.sf.net/mingw/msysDTK-1.0.1.exe?download>

Are all installed, I have reinstalled and rebooted a number of times still
no success
 MSYS - M4 <http://prdownloads.sf.net/mingw/m4-1.4.7-MSYS.tar.bz2?download>

Is not install for the reasons detailed above. Can anyone point me toward
the MSYS - M4 update for WIN32:

How can I overcome this error when installing the RTEMS tools for WIN32

Regards

Sam
