Is there such a file in your installation?
Have you a correct working version of the game (I mean either official CD or the rip about which you are certain it works)?

Mount the cdrom with "-t cdrom"

@mirekluza
The setup.mix file is in the installtion folder. And I have the orginal cd of command & conquer.

@Srecko
I do not understand how this should work. What have I to type in? Regulary when I mount my CDROM-drive i enter mount e e:/. When I enter -t cdrom the programm says to me that this is a illegal command...

You write:
mount d F:\ -t cdrom
where F is the letter of your cd-rom drive where the disc is in.

@[MBP]: READ README AND DOSBOX GUIDES !!!!!!!!!!!!!!!!!!!
If you had done it before, you would have known how to mount a CD ROM properly ...

Ok thank you it works!

But I have another Problem, the speed is bad!

I tried to enter ctrl + F8 and ctrl + F12 but the speed is as worst as before. What can I do?

A) Try Dynamic Core
B) Wait for New DOSBox Release or Download Unofficial DOSBox CVS (which I've tested this in and it runs very very well)

get a faster pc

ok i got the same problem, but fixed it 😀

but now there is another problem

the setup stops at 12 % 🤣

any help 😕 😕 😒

I can't get it to install anything......I select the sound card, test it, works fine.....then after I select ok, some setup unsucessful message pops up, setup file not found.....what the heck is this....

Did you make sure to mount your cd with the "-t cdrom" and mount a hard drive?
Otherwise (for Sierra games at least) if I fail to do so, the game tries to install onto the cd and fails miserably. Actually the problem is that the game thinks it's already been installed and is simply setting configs for the hard drive (which is actually the cd). Or make sure you have read/write permission to wherever you install the game onto.
By the way I think you may be running at too high cycles. Typically I run at about 10000 cycles maximum and on occasion only 5000 for some games due to sound issues (But that's just me).

😮 holy crap 200,000 cycles? What kind of computer do you got?

That's way too much for any normal computer.
Check to make sure you have mounted something like
mount C: C:\
mount D: D:\ -t cdrom
To install it from the cd of course.
Modify the above lines to what you do for your system though.

@dougdahl

It's quite handy that many of the Sierra programs acted that way. If you install it first from your CD to your Hard Drive them copy some of the files over. Then modify the lines in the resource.cfg to point to the directory on the hard drive instead of the CD you can play directly from your hard drive with no problems.
😀
I've done it with every Sierra game that I have. I think there may be a couple that don't work that way but the Adventure games do.

Man, I got the game running and at full speed and everything, but for some reason I click on a unit move it somewhere else and the game freezes as it attempts to move.....any suggestions?

uhm sound effects problem ...
try running without sound to see if it helps.

Yeah, runs faster too.....go figure....probably don't help my soundcard ain't supported really.....I selected Sound Blaster because it was the only one that seemed to work.....the card I got is Sound Max Digital Audio, which ain't selectable.....something tells me this game will only run without sound on my system which sucks royally....oh well, if anyone got a fix, let me know (for the sound)......anyone know if the net play works still on that game....would like to play online if possible with someone sometime.....

You might wanna check this out....guy claims he can get this game running in XP without DosBox or anything....I tried it but it didn't work.....the Soundblaster Fix did not work either......so I just thought maybe I'll just run the demo setup like it said, and of course it did fail like it says....I then copied the install files from the full version CD like it says......tried to run it not in dosbox like it says and set everthing up with the soundblaster emulator, didn't even load.....I thought, oh well, but it gave me an idea, I used the demo like it says, copied the files from the cd and then ran it in DosBox and for some strange reason the game runs now with sound and doesn't freeze when I move a unit......I think it's kinda strange, but at least I got it working with sound now I guess....just posting this in case no one can get it to work with sound....you might wanna try running the demo setup instead of the full version setup....it works, for some strange reason, just give it a try if you are having sound problems....

The game should work in XP shell. Just copy some mix files from cd to game directory (e.g general.mix, and all others except scores.mix and movies.mix- you can copy those too if you want music and movies). Then run it like this: C&C -CDC: (replace C: with the drive where your game is ). THis should disable cd checks. To get sound working it's a little more complicated (you need to have config file correctly set up for vdmsound or XP's SB emulation (SB/PRO/16 or Clone, irq 7 or 5,DMA 1,port 220).

@ priestlyboy
Yes, it is very useful. I've done the same thing myself a few times (and there are a few games that I wish did that as well).
But if you're not aware of what's going on, it's a real headscratcher as to why
the stupid game just refuses to install from the cd. I wasn't saying it was a bad thing, just that it could have been a problem.

worked for me 😁
