# Installing on Other Platforms

If TIBCO_HOME does not exist on the machine, its location must be specified when installing TIBCO Enterprise Message Service. All subsequent TIBCO software will be installed under TIBCO_HOME.

Install TIBCO Enterprise Message Service using one of the following modes:

- Installing in GUI Mode
- Installing in Console Mode
- Installing in Silent Mode
  Warning: The Universal Installer can install only one version of TIBCO Enterprise Message Service at a time. Expanding multiple EMS product packages of different versions into the same location for the purpose of having the universal installer proceed with installing them in one operation is not supported. In such a situation, expand those packages in separate directories and run the installer once for each package.
