# Installer Account

## UNIX

To install TIBCO EMS, you can login either as a regular (non-root) user or as super-user (root).

Except on Linux, a graphic environment such as CDE or X Window is required to run the installer in GUI mode.

Tip: For information about installing on UNIX systems, see DISPLAY Variable FAQ.

## Microsoft Windows

You must have administrator privileges to install TIBCO Enterprise Message Service. If you do not have administrator privileges, the installer exits. You must then log out of the system and log in as a user with the required privileges, or request your system administrator to assign privileges to your account.

If you intend to install the product on a network drive, you must ensure that the account used for installation has permission to access the network drive.
