MATLAB Installation Guide for Windows

Upgrade Installations

When upgrading an existing installation, note the following:

• Always install MATLAB in a new installation directory, even for upgrade installations. By default, the installer creates a new installation directory for each release, for example, MATLAB6p5.
• You do not need to delete an existing MATLAB installation before installing Release 13. You can run multiple versions of MATLAB on the same system.
• The installer does not overwrite existing MATLAB preference files on your system. Multiple MATLAB installations on the same system use the same preference files.

Note    Before Release 12.1, the uninstaller provided with MATLAB automatically deleted MATLAB preferences files. If you plan to remove an installation of one of these earlier MATLAB releases, you might want to first save your MATLAB preference files. See Saving Your MATLAB Preferences for more information.
