I am running Windows 7 Home Premuim 64 bit

When trying to compile any program with mingw's gcc or g++ I get these errors

I installed mingw with Code::Blocks with this installer codeblocks-10.05mingw-setup.exe
I have also tried using mingw64 which works fine till I try to run the compiled program. AT which point it says it is missing a library called libgcc_s_sjilj-1.dll

Does anyone know how I can get gcc working so I can compile my programs on windows?

EDIT: I got mingw64 working by adding the lib folder to the path

yeah I got it working by adding the lib folder to the path. thanks for the tips
