I had installed Yahoo messanger on fedora linux,but whenever i click on it nothing happens.Plzz help me

More information is needed, such as error messages.

Suggestion: start Yahoo messanger form command line. You may get error messages which could help solve the problem.

I had run yahoo messanger.This is what i got..

[root@Hardeep bin]# ymessenger
bash: /usr/bin/ymessenger: Permission denied
[root@Hardeep bin]#

Firstly, there's no reason to be running that as root. Use your normal user account for such things. Secondly, does the executable actually have executable permissions set?

I had also run that as normal user,but got the same prob.could u plzz tell me how to check execution permission and how to change permission.

thanks for ur support

Run "ls -l" (that's a lowercase L in both cases) to check the permissions. Here's an example:

-rwxr-xr-x 1 root bin 15736 2004-03-16 02:08 /bin/cat

The first column is the permissions and the 'x' is for executable. There are 3 of them, so that this file can be executed by the owner (root), members of the group (bin) and anyone else.

If you do not see a single x in the output, then you'll need to set the executable permissions. This is done with chmod. As root, run "chmod a+x ymessenger", which will set the permissions for everyone.

Edit: see "man chmod" for more info about chmod.
