Compiling problem :: Gcc can't be updated to 4.6 or greater

[G4BB3R]

Today I followed the github tutorial to compile on windows 8.
But even updating mingw, the message "Sorry, you need gcc 4.6 or greater to compile." still appears.
I verified the toolchain path, deleted the MinGW from Code::Blocks folder, and still not working.

Error log (half):
