New guy here too.
I too am having difficulties with the installation. I have installed several versions of Code::Blocks, MinGW, Min GCC.
The page referenced for this: MinGW GCC C/C++ Free Compiler, including GFortran - I get a blank page in my Firefox browser. In chrome it offers a 30 day trial.
One of the Code::Blocks and/or MinGCC downloads indicates the compiler is included and installed automatically. I don't find it.
My installation was on a different drive than Windows 10 but that should not matter. There is no compiler I can find to put in the path of my environment.
