Some applications is not working after upgrading from Ubuntu 11.04 32 bit to Ubuntu 12.04 64 bit

Question

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.

Answer 1

You can't restore your old applications for these reasons:

1. You changed your architecture from; this will make your old applications useless.

2. Some of the old applications maybe not supported anymore in Ubuntu 12.04, so some of them may be lost.

You will have to install your favorite applications again.
