I think I had the same issue installing WC2 from CD. Problem is, I don't recall how I solved it, I've simply been copying it from one PC to another since.
I've attached a zip file containing my install.dat and wc2.cfg files. Maybe it'll help to unzip them into your WC folder.

Hi, I placed those two files both in

c:\wing2\gamedat

Went back to D drive(CD-ROM), launched (wc2.bat), but there's no sound at all. What have I done wrong? Thanks.

Set SB IRQ to 7 in your dosbox.conf (I' made a new one for WC2 actually). Maybe you'll have to add the following line to the autoexec section: set blaster=a220 i7 d1 t6

NO!

DOSBox will automagically create the correct BLASTER variable based on the other settings in the configuration file.

Whoops, sorry 😅

At least it hasn't blown up my PC yet... 😊

My SB IRQ is already set to 7

The game worked for me "out of the box" (sound and all):
mount c c:\games\old
mount d d:\ -t cdrom
d:
winstall.bat
"Select save game drive:" - picked C
"Sound System Installation" - picked Creative Sound Blaster
"Speech selection" - picked Yes
"Sound Blaster Pro DMA Select" - picked DMA 1
"Correct config?" - picked Yes
"Installation complete." typed wc2 at d:\> and voila.

PS. I recommend creating a CD image. Having the game load data from the CD makes the game stutter.

winstall.bat ?

You installed and played the windows version?

Winstall.bat does not install a windows version of the game.

edit: I don't know if it's meant for installing within Windows, but it works in Dosbox.
