2. Installation
The following features are new or changed at Release 16.0. Please review these items carefully.
• The installation program detects and informs the user when a computer restart may be required because
prerequisite components necessary for the installation of the ANSYS products were installed.
• ANSYS, Inc, products and the installation program will no longer support Windows XP.
• ANSYS, Inc, products and the installation program will no longer support Windows 32-bit systems.
• If the product installation is able to query your license server, the installation screen options are pre-selected
based upon the information from your license server. If the installation program was unable to query your
license server, this message is not displayed and the default installation options are selected as in previous
releases. Note: CAD selections must be done manually in either case.

• A new installation progress bar has been added to display the time remaining during the installation process.
• New options allow you to install the product documentation to any location or elect not to install the product
documentation.
• ANSYS Composite PrepPost is now included in the product installation and can be selected on the product
selection menu for installation.
3. Licensing
The following enhancements have been made to ANSYS, Inc. Licensing for Release 16.0:
• The ANSYS Meshing product now supports ICEM CFD and TGRID meshing.
• The Product Order file was updated. If you typically change the default order in which products are checked
out, be certain to re-order the licenses using this latest version, via the ANSLIC_ADMIN utility.
• Licenses containing TRL encryption are required to run the 16.0 License Manager.
• HPC Parametric Pack licenses now apply to the ANSYS Aqwa Suite and the ANSYS Aqwa Suite with Coupled
Cable Dynamics products.
• The ANSYS License Management Center is replacing ANSLIC_ADMIN as the tool for most license adminis-
tration functions.
– The ANSYS, Inc. License Manager Start Menu has been modified to include the ANSYS License Manage-
ment Center option.
– To support the ANSYS License Management Center, a Tomcat web server and a version of Java will be
installed within the license manager directory during the ANSYS License Manager installation .
• The ANSYS License Manager now supports both ansyslmd and ansoftd licenses using FlexNet's Common
Vendor Daemon (CVD) technology. During the License Manager installation, if the FLEXlm for Ansoft (ansoftd)
is installed, it will be shut down.
• The following changes have been made to the licensing file structure:
– The default directory containing the license file has been changed from licensing to the new licens-
ing\license_files directory.
– The new default license file name is ansyslmd.lic. Additionally, any file with a .lic file extension
in thelicense_files directory will be recognized as a license file.
– Your existing license file will be automatically copied to the new location during the licensing installation
configuration process.
– Electromagnetics (Ansoft) license files are also stored in this directory.
• Windows XP and 32–bit platforms are no longer supported.
4. Documentation
Documentation is now installed per-product; only the documentation associated with the products you
install will be included by default. You can choose to install all documentation by running a document-
ation-only install from the installation launcher.
