Trouble installing balkans. Anyone can help ?

[pigifly]

Hi All.
I have a problem installing the balkans theaters.
Whenever I launch the installer I get a windows saying that "exploere ha caused an error etc etc etc"
Is there something I could do to install it?
I'm on win98 ..
the full message is ( sorry, is in italian ) :
