Assuming that you did all the other steps correctly, you probably just need to set the permissions to make the file executable.

In a terminal--in the directory where the file is:
Code:

ls -l filename          ##to show you the current permissions
./filename              ##to attempt to run(execute) the file
sudo chmod +x filename  ##to set the file "execute" bit on.

Synaptic should be under System->Administration in the Ubuntu menu. It might be called just "Package Manager" or something.

@Roisin: "There is no installed viewer capable of displaying the document."

The first question must be: what type of document are you trying to display?

You should post more details question..!
Try using terminal to open app! (view name of command in icon's properties tab)
using dpkg to query!
