For new user trying it output:
[D:\OpenTTD]openttd
Error: No available language packs (invalid versions?)
the important thing to look for is to check what version you're trying of OpenTTD and download the Windows-32-bit .zip (for OpenTTD 14.1: "openttd-14.1-windows-win32.zip") package that contain all the files needed, unpack them (except openttd.exe) next to openttd.exe by Paul.
Hmmm trying setting the set lang to en_us....
It might fix it :-)

Hahaa, If one just download the huge openttd.exe from here and try it, one get that message. One has to also get the Win32 .zip and unpack the files to the same folder and to actually make it work. Language doesn't matter, the message is misleading that way.
I would like to get a screen captures of how to retrieve audio and music in german, english, french, italian, dutch and swedish to complete the wpi I've put together. The problem here is that screen capture doesn't work with sdl2 window, so someone that run it in a virtual machine can get it?!
