I updated my system from Ubuntu 11.10 32-bit to Ubuntu 12.04 64-bit using installation DVD. I used option 'update older installation of Ubuntu 11.10'. Now my softwares and settings pre-installed before update are not recovered within Update setup. They are still stored on my hard disk but I can't use them as I used to earlier. How can I recover my older installed softwares and settings.
You can't restore your old applications for these reasons:
You will have to install your favorite applications again.
