So when you ran it in a terminal there were no messages of any
description, and the prompt returned? That indicates that:

a) the program exists
b) the program is in your PATH
c) the program was able to be executed
d) the program produced no output to the terminal

... the first three of which are good things!

Check /var/log/syslog as well, it may log errors there.

You could try looking in the task list for likely candidates, i.e., in
a terminal window:

   ps ax

You could also try

   apropos boinc

to see if there are related man pages (also try whatever words BOINC
stands for).

Each of those icons has a desktop file. Customised ones are generally
in ~/.local/share/applications, distributed ones are generally
in /usr/share/applications/, autostarted programs are generally in
~/.config/autostart, so check out those places first. To find all the
places they could be, use locate:

   locate .desktop | less

It's quite a list. Local ones override distributed ones if there are
files with the same name in multiple locations.

There is probably a config file somewhere that says what locations the
Launcher should look in for desktop files, but I don't know what that
config file is.
