1) Download <filename>.deb file, save it in the "Downloads" folder.

2) Open "Downloads" folder and start Terminal app in this folder.

3) If you have 32-bit machine, skip this step. Otherwise, run the following command:

	sudo dpkg --add-architecture i386

4) To install application run the following command:

	sudo apt-get update; sudo apt-get upgrade
	sudo apt-get -y install ./<filename>.deb

   In case you get a message what some dependencies aren't installed, run the following command, and then try install again (the second command above).

	sudo apt-get -f install


That's all. You can now run installed application by clicking its shortcut on Desktop.


*	- replace <filename> with real name of the file.
**	- you may need to reboot your machine after step #4, because installer also updates some system files that may be in use.
