Please consider adding a warning when the compiler executable is not found during installation.
For example, if you install the MinGW C compiler (rather than the C++ compiler), and then install Code::Blocks, it defaults to mingw32-g++.exe which is the C++ compiler, even when the file does not exist. If the file is not found, it should either default to mingw32-gcc.exe if it is found, or produce an error message so the users knows that the installation/configuration was incorrect or incomplete.
Thanks.
