Installing VisIt on Linux (and optionally on Mac OSX) is done using the
visit-install script. Make sure that the

The version argument is the version of VisIt being installed. The platform argument depends on the type platform VisIt is being installed for. The platform argument can be one of the following: linux, linux-x86_64, darwin. The directory argument specifies the directory to install VisIt into. If the specified directory does not exist then VisIt will create it.
For example, to install an x86_64 version of VisIt 3.0.0, use:
visit-install 3.0.0 linux-x86_64 /usr/local/visit
This command will install the 3.0.0 version of VisIt into the
/usr/local/visit directory. Note that when you enter the above command,
visit3_0_0.linux-x86_64.tar.gz must be present in the current
visit-install script will prompt you to choose a network configuration.

The VisIt installation program adds a VisIt program group to the Windows
Start menu and it adds a VisIt shortcut to the desktop. You can double-click
on the desktop shortcut or use the Start menu’s VisIt program group to
launch VisIt. In addition to creating shortcuts, the VisIt installation
program creates file associations for
.session/.vses files so double-clicking on files with those extensions
opens them with VisIt.
