Hi Louise, My suggestion is to go to Cygwin (www.cygwin.com), download setup.exe (I usually save it to a file called CYGsetup.exe), run it, click Next through to the packages page, change the top level "All" package from "Default" to "Install", click Next, get a nice hot cup of tea, watch a movie, read the paper, check the progress, watch another movie, come back, exclaim "At last, it's done!", and then run the Cygwin bash shell, type 'gcc --version' and say "GCC is working! Yippee!" Make sure you have a lot of hard drive space, a good internet connection, patience, and time. HTH, --Eljay
