Either the application requires special hardware features or the vendor decided to not support your computer type" if i go to software center i get this error

The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used.

Which Ubuntu version are you using? – Javier Rivera Apr 9 '12 at 9:03

Have you checked if you are able to connect to Internet? If yes, update the software list first

sudo apt-get update    

sudo apt-get install ubuntu-restricted-extras
