Too difficult for me

Hi everyone,
What to do if the install file is not marked as executable ?
This file is now on a CD.
How do I change the permissions ?

Files on a CDROM are not modifiable.
If it's a script, you can use <interpreter name><file name> (ex: bash
myScript.sh)

Thanks for this answer.
Two remarks :
1) I am now using GNU/Linux Ubuntu Lucid Lynx : the install file isn't marked as executable
2) Before I was working with Karmic Koala and no problem to install the software with this CD.
An idea ?

You should be able to change the default permissions that CDs without
permission support gets mounted as...

See the mode mount option for iso9660 in the mount man page:
http://linux.die.net/man/8/mount

If your distribution is mounting the CD on your behalf, you should ask
their forums / mailing list how to mount / remount it with different
options...

Short version of things to try:
As root, run "mount -o remount,mode=0777,exec /media/cdrom" # Adapt
paths for your CDROM's actual path, potential security issue 777 might
be overkill...

If it used to work, it might be a good idea toreport it as a bug in
Ubuntu. (Which they will probably close as wontfix, because of
potential security issues)
