Foss Rain: How to Install .run files in linux

Occasionally, some applications and games have .run installers which is a bit awkward to see rather than compressed or .deb files. This is similar to what .exe installers do on Windows and is different to the normal methods (at best, using the Software Center, at worst using .deb files) in which applications are installed in a standard way and can be easily removed.To Run the .run applications we must

• make it executable
• and run it

There are two ways to make it run and instal it in your device i.e. Graphical way and Terminal way

Graphical way : 

     1) Find the .run installer file in your system

     2) Right click it and go to properties

     3) click in the permission tab

     4) Tick the box saying "Allow executing file as a program"

     5) Double click that .run installer file (run in root mode)

Terminal Way : 

Suppose that i am want to run same xampp-linux-x64-5.5.24-0-installer.run file and it is in the folder /home/kauseek/Downlads/run then follow the below terminal commands to run it

1. Open Terminal(ctrl+alt+t)
2. enter cd /home/kauseek/Downloads/run
3. enter chmod +x xampp-linux-x64-5.5.24-0-installer.run
4. enter ./xampp-linux-x64-5.5.24-0-installer.run
5. If step 4 fails with message "Permission Denied" than try entering the command sudo ./xampp-linux-x64-5.5.24-0-installer.run and for this command you will need your administrator password
