I've downloadad the latest XAMPP file, to install it into Ubuntu 13.04.

After downloading the file, I just can run it.

I've double click it (and I've tried right click and clicking "open", whith the same result).

All the answer I get is this message:

Could not display “xampp-linux-1.8.3-1-installer.run”. There is no application installed for “executable” files. Do you want to search for an application to open this file?

I've tried searching for an application, with no result...

Also, I haven't found any questions related to this issue with the 13.04 Unity version... I've tried this solution, with no result.

Please note that this isn't a Xampp question, the same happened to me when I tried to install Skype.

UPDATE:

I've tried this solution:

cd ~/Downloads

chmod +x myfile.run

sudo sh myfile.run

And I've got this error:

Syntax error: "(" unexpected

What should I do? Thanks!
