Always install from the repositories. It configures the programme properly
and makes it available for all programmes that might require it. It also
makes removing the application and upgrading it much easier. Installing
manually from binary or tarball is only for people who who know what they
are doing. Going outside the repositories is NOT recommended for anyone
other than advanced users. That way you can only blame yourself and are
prepared to fix the problems that you create.

The repositories are safe, secure and maintained by the same people who
produced the distribution. Use Synaptic and install from it or the Software
Centre. The Windows method of searching for applications on the internet and
using various different installers produces a mess on Windows where there is
no uniformity and anything can and usually does happen, leaving users with a
mess to clean up in the menu, system tray and on the desktop, to say nothing
about potential viruses, malware and the like. Do yourself a favour and
forget these bad habits. Windows is Windows and Linux is different.

The problem is now you don't know where the problem lies. There could be
residual problems from your initial installation. To blame it on Ubuntu is
not fair since you did not use the normal and recommended practice. It is
also not fair to single out the 64-bit or 32-bit version either. I use both
64-bit and 32-bit versions and they work fine on their respective
computers.

You ask a lot of questions, but you don't seem to listen to advice.
