open your terminal and type as this dpkg -s <your_app_name > and look at the status field . – Raja Jul 22 '12 at 3:54
well it shows following msg ubuntu@ubuntu:~$ dpkg -s chrome Package `chrome' is not installed and no info is available. Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents. Is there any way shoul I save these before shutting down.? Thnkx – ravishingrude22 Jul 22 '12 at 4:25
ok previously how you installed them ? – Raja Jul 22 '12 at 4:42
I installed chrome from internet and it was running fine in the last session of ubuntu – ravishingrude22 Jul 22 '12 at 6:07
Are you by any chance running directly from the liveCD, and did not install Ubuntu to your disk? It sounds exactly like that. When running from CD/DVD, all changes you do (including additional software installed) are lost as soon as you shut down. – Izzy Jul 22 '12 at 9:51

try to press the "windows key" and search for chrome.

Open the dash (super key or click top of launcher), and start typing the name of one of the programs. It should search and find it for you.

Thanks but it works fine on current session as soon as i restart my system ..everything seems to be disappeared as if they were never downloaded and I can't find them in the dash even... – ravishingrude22 Jul 22 '12 at 4:15
Odd. Does Ubuntu Software Center still show them as installed? – Jazz Jul 22 '12 at 4:18
Another thought, you aren't running off the live cd are you? – Jazz Jul 22 '12 at 4:19
No, Software Center does'nt show them either...Also I m running ubuntu 12.04 from a USB stick.. – ravishingrude22 Jul 22 '12 at 4:22
If the USB isn't made with persistence mode it won't store your installed files. Whatever you are experiencing that is expected. – Web-E Jul 22 '12 at 4:55
