how to install not using sudo?

[dakota]

hello sorry for such a simple question, but i have a copy of peazip and am curious how i can install it on a machine that is not online so no simple sudo commands... the file is peazip-5.3.1.LINUX.GTK2.tgz i also have a copy of winrar i want to install both do not have self installation when i try to open the file, if you can happen to know a site that explains how to install or the process in what to do i would be grateful. i figure this is something i need to learn anyway!

thanks,
dakota
