appropriate place for software so that all user can have access it

[linux.ab]

hi..I want to know the exact place for software so that all user can have access it ..e.g I have installed wine as root user...I have also installed utorrent and use it as root user...when I changed user I cannot access utorrent....to use it I have to copy it from root user...so I want to know where should I place the software,in this case, utorrent,so that besides root,all user can have access it without difficulty....kindly help me in this regards
