For sure, this user has downloaded the first windows C::B link, so without compiler.
For the next release, I suggest to change the order of the downloads for windows and put at the first link the version with compiler for admins.
The note indicating "If unsure, please use codeblocks-17.12mingw-setup.exe!' should also be placed before this first link and in italic, as it is, but also in bold characters.
Obviously too many (noob) users click on the first link they find without reading the page.
