hi,
i installed gt4 in my root login.i had my packages in desktop and installed them from there.but i didnt create any specific directory for installation.can anybody tel me where they get installed?

And in gt4 installation guide am instructed to login into a "non-root user" and pick an installation directory to install all softwares.so can u tel me if i can use all these softwares from some other non-root login or shd i install them all in tat non-root login anew ?
