You should try to provide some more details when requesting help in the future. However, oddly enough, I think I actually know exactly what you are talking about.

Instead of running this in DOSBox, you can run it on the Windows XP command prompt if you start it using
SWING.EXE NOLINEAR

It seems to be pretty strict about its CD check (if the check fails, it tries to start as a network client), so that's probably your best bet.

you can run it on the Windows XP command prompt

Linux guys will love you for this answer.

Of course fixing the mounting might work, too.

Read my 60 Seconds Guide to DOSBox.

If that doesn't help, come back with details on how you mounted your C and D drives, how you did the install, how you configured sound, music etc.

I tried to run Swing with DosBox v. 0.65, 0.70, 0.72 with floowing config:
mount c e:\swing
mount d -t cdrom e:\swing
c:
swing

V.0.65 runs only startup screen of the game. @ newer version reports about "You started as network client" problem on start of new game or load old game.
Sound works OK.
OS - WinXP SP2.

Bad installation, see

Yep, I wrote there too.
Unfortunately Software2000 company doesn't exists anymore. Where the game can be found nowadays?

Did you actually READ what that last guy wrote?

I had the same problem (network client) then I started up like this:
mount c J:\games\swing
mount d J:\games\swing -t cdrom
c:
swing
I get another loadingscreen and I could choose a New Game. hope its works for you..

Yes, I've read. And I don't see difference with my config.

Put the stuff into something like e:\oldgames\swing and mount the
e:\oldgames directory instead of the swing directory directly.
Isn't there an installer on the cdrom anyways?

Re: difference

1) mount d -t cdrom e:\swing
2) mount d J:\games\swing -t cdrom

See the difference?

It is not a difference. I tried both ways to set this command.
Looks like wd is right. I have damaged installation and already don't have a CD. 🙁
Looking for correct installation...

Still there might be a difference in the mounting, as you don't know in which
directory the poster's game is (e:\swing or e:\swing\swing), see my last reply.

Oops... Sorry, wd. I forgot to update you that your advice to add internal folder didn't help.

I created e:/games and put whole swing folder there. Then I updated mounting lines to point e:/games/swing.

Interesting that swing.com recognizes that there is CD-ROM as drive D:, but it reports "No Swing CD found" before running the graphic environment.

One question that pops up in my mind is this:

How does the application know that the CD should be in drive D? Why not in drive E, F, G, H, or any other drive letter?

Hmmm... Really... Only 26-4=22 attempts to check all options... 😲
On my old machine in 1998 it worked without any CD in CD-ROM.
It works for other people when CD-DOM assigned to drive D.

Then I updated mounting lines to point e:/games/swing.

Well the point of the whole thing is to mount e:\games and not the
swing subdirectory. But no idea if that helps, yet it is how in general
you should organize games/installations in dosbox anyways.

Did you solve this? It ought to work if you do it this way (like wd is saying):

mount c e:\
mount d e:\swing -t cdrom
c:
cd swing
swing

It works for me in linux, only diifference is that I have all my games in a "dosgames" dir.

game might be looking for a device then.
Can you post the contents of the swing directory when you have run in in linux ?

HappyFrog - thank for effort. It doesn't work too. 😀

Qbix - here you have (but I run DosBox under WXP).
