AFAIK you also have to be administrator to install things in r"C:\Program Files". If you install something user-only, (which more software supports than many people think) it ends to somewhere in the user directory. I always thought that installing things in "Program Files" rather than the root directory was just good manners (just like installing things in /usr/local or /opt on GNU/Linux) > Depends on the Windows version.
