Redguard will probably look for a subdirectory, not the root directory, that you are mounting, the mounts need to be exactly the same as when you installed. Install the game from within DosBox.
I don't know where it is advised, as I don't own that game, to set affinity to 1, but unless critical and advised somewhere (maybe incorrectly, as DosBox uses one core anyway), I wouldn't do that or bother with it.

I can't figure out how to install the game using dosbox. Installing the game through the windows installer doesn't give me an option where to install.

Are you really have the retail version of Redguard? Because as I can see myself right now - there is a choice "where to install". And there are 2 cds.
1) Install the game in windows.
2) Copy installed gamedir to the catalog mounted as the dosbox c drive.
3) Run DOSBox.
4) Mount cd2 as cd-rom drive within DOSBox.
5) Check system.ini/[system]/animation_drive, must be d:\
6) Execute sound\setsound.
7) Run the game with rgfx.exe.

The last Ykhwong's build (6 may 2013) isn't working with this game (invalid descriptor 0 int 21), previous builds are working. No, all is working ok. I have just forgot to return memsize=63 (memsize=16 is using for Battlecruiser 3000 A.D.),

The problem was I didn't uninstall the previous one properly. I have 3 files from 2 CDs: Install cd ISO and Play cd BIN/CUE. Sorry 😅

-Mounted the Install ISO on a virtual drive F:\ and installed Redguard to my second hard drive "D:\Games\PC\TESIIA - Redguard".

-Both cds are in the folders CD1 and CD2 respectively within the same directory.

-Extracted the DOSBox build into the same above directory and deleted glide2x.dll

-animation_drive=d:\ - check

in dosbox:
mount c "."
mount d ".\CD2" -t cdrom
c:
rgfx

I get "critical disk error, redguard can not run."

use mount d x:\ -t cdrom, where x - cd drive (may be virtual) with inserted Redguard cd.
Or use imgmount d "y:\cd_image_file_name" -t cdrom to mount cd-image.

You're trying to mount a dir as an image, from what I gather.
You're doing this

1mount d ./CD2 -t cdrom

instead of this

1imgmount d ./CD2/somename.cue -t cdrom

The first will yield this if looked at under DosBox using the commands below

1d:
2dir

Directory of d:\.
somename.cue xx xx-xx-xxxx xx:xx
somename.bin xx xx-xx-xxxx xx:xx

That's NOT what you want.
Use imgmount or you'll just go in circles with no solution in sight.

Actually "imgmount d ./CD2/somename.cue -t cdrom" is what I used, amongst other things, including the first one.

Edited the last post,

1mount c ".\Redguard" 
2imgmount d ".\Redguard\playCD\Redguard-cd2.cue" -t iso 
3c: 
4rgfx

Still gives me the Disk Error.
"c" is the install dir, where rgfx.exe is

As previously stated:

Instead of using

1mount c ".\Redguard"

try

1mount c "."

But that might not work either. As previously stated, the game may be expecting to be run from the same directory to which it was installed, namely "D:\Games\PC\TESIIA - Redguard". Of course, DOS does not recognize long file names, so DOS will see it as D:\GAMES\PC\TESIIA~1.

That means you'll have to use

1mount d d:\

and then use

1cd GAMES\PC\TESIIA~1

before running rgfx.

If it still doesn't work, you may have to mount the CD images as drive F in DOSBox and use -animation_drive=f:\ , because that is the drive that the game was using when you installed it .

The problem it seems was, like people were telling me, a problem with file names and placements. And that Redguard looks for a subdirectory in "C". So...

1mount c "."
2imgmount d .\cd\Redguard-cd2.cue -t iso
3c:
4cd\game
5rgfx

And it works like a charm!
Well, sound does stutter at loading, but every game I play through dosbox does.

Thank you.
