Hi, If I understand well what the Howto use explains (http://forums.next.codeblocks.org/index.php?topic=3232.0 (http://forums.next.codeblocks.org/index.php?topic=3232.0)), a nightly build version of C::B doesn't need any installer programm, I mean a setup.exe file. True ?

The nightly builds are provided just as a bunch of files compressed in 7-zip. You decompress them wherever you want and it (Code::Blocks) will work from there (of course, you need the wxWidgets' DLLs and Code::Blocks' binaries).
Now, to install a compiler you'll surely use an installer, even though MinGW can be installed in a similar way (using compressed files), but it's another story.
So... true, no setup.exe for the nightly builds... no need for one either.
If you have WinRar, it will handle 7zip files.
