Without breaking the forum rules re: piracy; what I can say is, most programs will be stuffed in .sit format or dmg files. For sit files you should drag & drop onto stuffit expander. For dmg files, drag & drop onto disk copy (found in utilities folder) which will mount them. Make sure you have permission to install programs in your account. Otherwise you may need to ask whomever has admin priviledges to install them for you.
