You can copy to another system, but you won't have the registry settings that are done during the installation.
To fix the language, save the following as a *.reg file then run it. You can also simply make the registry change yourself in regedit:
Windows Registry Editor Version 5.00
If you look in the "C:\Program Files\ESTsoft\ALSong\Language" folder, you'll see the actual language resource DLL.
Let me know how that goes or if you need any other help.
I really like Kimo. It's strange when you think of ukelele, but man - He just SMOKES!
