Hi. I just installed LibreOffice 5.0.2.2. But I am unable to get it in
Application's System menu. What can I do to get installed properly. I am
using Kali Linux OS.

Did you install it from the repository? Normally it is best to install a package from the distro's repositories. Occasionally there is a tweak the distro maintainers must make for everything to work correctly. Also, check Kali's help pages, there may be a fix posted.
