The installation works, it creates the following executable files:
Digplay.exe --> This program plays one or more .wav or .voc files simultaneously using any Soundstream-compatible digital audio driver
Dos4GW.exe --> creates fatal error : Syntax is Dos4GW <executable.xxx>
Fixboot.exe--> nothing happens
Memsetup.exe--> This program has forced ZN to act as though your system has the minimum amount of memory. Please refer to ZNEMHELP for further information
Nemreg.exe--> starts the electronic registration
Setsound.exe--> opens sound setup but the sound already works properly
XMIPlAY.exe--> This program plays one or more XMIDI sequenses simultaneously using any AIL 3.0-compatible .MDI audio driver
ZNSetup.exe--> kills dosbox
Zorkdos.exe--> Zorkdos is not a watcom program
Zorkuvbe.bat--> ZN needs VESA BIOS v 1.2, UNIVBE simulates this bios but the installation of this program does not change anything
