Hi,

I have a problem, when I try to install Comsol 4.0a on Ubuntu. When I run this comand :

francesco@ubuntu:/media/FRaNK/PROVA/COMSOL40a$ sh setup

setup: 497: /media/FRaNK/PROVA/COMSOL40a/bin/glnx86/setuplauncher: Permission denied

It return by "ACCESS DENIED", how I can solve this problem?

Thanks a lot.

The OS thinks that the CD is write protected (which it is of course) and it won't allow you to run setup. You need to change your permissions or copy the contents of the CD to a temporary directory and run from there. The best option is to have the CD on the local machine, then run setup from another directory besides the directory the CD is on. For example:

cd /home/userid
/media/cdrom0/setup

Another reason could also be, that you don't have the permissions to execute the installation file.
As root (i.e. administrator), the following command could help (optionally after having copied the CD to a temporary folder on your local machine):

chmod u+x setup.sh (gives execute permission to the owner of that file) or
chmod a+x setup.sh (gives execute permission for all users for that file).

You might also have to do this for other files, that are executed during the setup procedure.

Hope that helps,
Juergen

Related to this problem, I had similar issue installing COMSOL on our cluster. I do not have root priv on the cluster, but do have root priv on my local linux client machines. So, what I did was mount the COMSOL install CD on the local desktop (client) linux box and called it local:/mnt/cdrom. Then I logged into the cluster remotely, and issued the following command:

mkdir comsol_cd_image
cd comsol_cd_image
scp -pr local:/mnt/cdrom/ .

This will create an image of the COMSOL install CD on the local directory of the remote cluster. From there, I can run the linux installation process without admin or permissions problems.

When you run a command on linux that needs administrator privileges you have two options:
type:
user@linux ~ $ sudo setup

in the cdrom directory, (it will ask you for the root password)

or:

user@linux ~ $ su

it will ask you for the root password, to log as superuser and it change to:

user@linux ~ #

the # symbol means that you are administrator, and from here just type : "sh setup"

I hope this is useful for someone.

Sorry, in the first line i meant:

user@linux ~ $ sudo sh setup

or

user@linux ~ $ sudo ./setup

is the same.

Hello

I'm trying to install COMSOL in Linux, but when the Installer is in the Install tab and I press the buttom Install to continue, it appears an error message:
"Not possible to create installation folder"

What can I do?

Are you installing as root or a normal user ? The default file installation location, under /usr/local, normally requires root access. You can change this to your home directory in order to install as a normal user.

I was using a normal user, so I changed to a root user and it's working! I hope installation is ok.
Thank you!

francesco@ubuntu:/media/FRaNK/PROVA/COMSOL40a$ sh setup

It return by "ACCESS DENIED", how I can solve this problem?

Thanks a lot.



you need to change the permission of file ("setuplauncher) by using chmod command
like
chmod a+x bin/glnx86/setuplauncher

then type:
sh setup

it should work.
