Help with XAMPP

Hello everybody.

I'm new using Piguy (well, twice weeks).

I want install XAMPP. I used:
1.- cd Downloads ( before I downloaded the installer)
2. sudo chmod 755 xampp-linux-x64-1.8.3-1-installer.run
3.- sudo ./xampp-linux-x64-1.8.3-1-installer.run

But in the point 3 I get:

========================
root@pimienta:/home/monica/Downloads# sudo ./xampp-linux-x64-1.8.3-4-installer.run

Welcome to the XAMPP Setup Wizard.

When it finishes installing I get:"Setup has finished installing XAMPP on your computer."

And not open the GIU for the configuration.

I hope you have understood me. I don't speak much English o.O

Thank for read.
