Installing Code::Blocks on Windows
1. Go to the official website of Code::Blocks, on the download section. Here is the link: www.codeblocks.org/downloads/26.
2. Download the file codeblocks-20.03mingw-setup.exe, unless you are using a 32 bits machine, in which case you must install the 32 bits version (codeblocks-20.03mingw-32bit-setup.exe). Note that unless your machine is very old, it probably is 64 bits.
The files with a name containing 'mingw' include the compiler set MinGW (Minimalist GNU for Windows) which is a version for Windows of the GNU/Linux compilers of the GNU Compiler Collection (GCC). The other files do not include compilers and require a compiler to be installed separately. I recommend installing Code::Blocks with MinGW.
The archive files (.zip) can be used to install Code::Blocks by simply extracting the archive instead of using an installer.
3. Execute the installer you just downloaded.
4. The IDE Code::Blocks should now be installed on your computer.
