Install notes for LD2:

Unzip -d to (say) C:\TEMP.
SUBST A: C:\TEMP.
Start INSTALL from A: 
Make sure you select to install from A: within INSTALL.

the game can be installed from the root directory of any drive.

install.ex! is the copy that originally came with this cracked archive.
install.exe is a modified version (no idea where it came from) that actually works in dosbox.
however, the game still does not run after installation.  I get a "fatal error 4" in dosbox.
this copy of this game does however work on real 486 hardware on dos 6.22, so it is not tagged as [b1]
