I am trying to install Sims 3 through play on linux, but I have been unable to actually mount the image to begin the installation

I have a dvd with the image that runs flawlessly in windows, but will not mount in ubuntu, I also have the image file that I have not been able to mount from my hdd, my external drive, or any other combination of things that I have tried

After searching through forums for the past couple days, I have found the following suggestions, but none of them have worked:

1.Install scripts to mount the iso from a hard disk
http://www.ubuntugeek.com/mount-and-...ning-them.html

-prompted for password, see the notification with the correct iso and location, then I get an error message from ISO mounter that says, "Cannot mount!"

2. Mount dvd manually
http://www.cyberciti.biz/tips/how-to...der-linux.html

$mount /media/dvd
mount: can't find /media/dvd/ in /etc/fstab or /etc/mtab
$mount /media/cdrom
mount: no medium found on /dev/sr0

3. Mount using gmount-iso
http://www.ubuntugeek.com/easy-way-o...in-ubuntu.html

-with .iso file on hard drive:
-selected .iso file for "image file (.iso)"
-selected empty folder (after a bit of trial and error) for "mount point"
-error: "An error occured
wrong fs type, bad option, bad superblock on /dev/loop0, missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so"

(I don't know if I'm using this program correctly, honestly)


I've never tried to mount an .iso inside of ubuntu before and would really appreciate any help that you could give! Like I said, I do know that the dvd is good - it runs in windows, and I also know that my cd drive is good as it mounts other cds and dvds fine.
