INSTALLING DOWNLOADED ALTERA SOFTWARE
9 ■ ALTERA SOFTWARE INSTALLATION AND LICENSING ALTERA CORPORATION
Installation Prerequisites
You should be aware of the following information before you install Altera
software:
■ You must have system administration (Administrator) privileges
(Windows only).
■ Commands that do not fit on a single line in this manual are indicated
by indentations of subsequent lines (Linux only).
■ By default, the Altera Installer installs Altera software in the <drive>:\
altera\<version number> system directory for Windows, and the
<home directory>/altera/<version number> directory for Linux, where
<home directory> is the default directory of your Linux workstation, or
is set by your system administrator, and <version number> is the
number of the Altera software version. If you use a different directory
name, substitute the appropriate name for <system directory> in the
installation steps.
■ When you specify the installation directory, ensure that you use only
alphanumeric characters and do not type any special characters or
symbols, such as !$%^&*<>, empty spaces, or non-English characters
into the installation directory. Including special characters may
invalidate the installation location.
■ Ensure there is at least 10 GB of free disk space to contain copies of the
uncompressed versions of the installation files. An additional 40 MB of
disk space is required for temporary installation files. Free disk space
requirements for individual software are described on the Download
Center of the Altera website.
■ You can install multiple copies of the same version of Altera software
on the same computer. Subsequent installations of the software can
have a user-defined name. When you install an Altera software service
pack on a computer that has multiple copies of the same version of the
Altera software installed, you can choose the copy of the Altera
software that receives the service pack.
■ If you want to preserve project compilation databases from an earlier
version of the Quartus II software before installing a newer version,
Altera recommends that you open the design in the earlier version of
the software and export a version-compatible database for the design
by clicking Export Database on the Project menu. After you install a
newer version of the Quartus II software, you can import the database
by clicking Import Database on the Project menu.
