HyperWorks 2023 suite contains independent product packages
Independent product packages give you the flexibility to download desired packages as needed. Any HyperWorks 2023 SA (standalone) update package can be installed either on top of an existing 2023 installation or it can be installed independently without the prerequisite of a 2023 base.
Important: You can no longer install a different version of an already installed product to the same location (for example, HW Desktop 2023.1 on top of HW Desktop 2023).
Installer capabilities and features
HyperWorks 2023 brings with it the robust capabilities and features of HyperWorks 2022.3 installers, as well as additional support for HotFix installers. These HotFix installers are quick patch type installers that are used to install on top of a prerequisite base installation, unlike the other full installers. These are marked with the word “hotfix” in the installer name and bring with them the quick fixes and features to better suit your needs.
Model files removed from installation package
To reduce the footprint size, the following tutorial model and demo model files are no longer included in the local installation. You can now find zipped tutorial model files and demo model files on Altair One via the Altair One Community and Altair One Marketplace sites. Altair recommends that you create an Altair One account and use it as your primary portal to access product documentation, a Knowledge Base, and customer support.

Known Issues

The following known issues will be addressed in a future release as performance of the software is continuously improved:

  • Some installers may fail to install properly if the Windows Regional Format is set to Arabic or Hebrew. The workaround is to set the Regional Format to English, or a different format.
  • On Windows 11, the shortcut icons for server and client mode installations are blank unless remote paths in shortcut icons is enabled in the Windows group policy editor.
  • Using the Back/Previous option with an installer may not reset the installer variables correctly if changes are made and the install session is continued.
  • On Linux, installing to a directory with spaces is not supported. Additionally, if the path that the installers are run from contains a space, you will see a harmless message in the terminal window.
  • Special characters in the path to the temp location can cause the Java in the installer to not function correctly.
  • On Linux, during a console mode install, when using the response file output command -r in the Help Configuration response file may not write out correctly.
  • If there is not enough TMP/TEMP space on the main drive (for example, C: under Windows), the installer will prompt you to input a new location. Some Java TMP/TEMP space will still try to go to the main drive even when selecting this new location.
  • Click Cancel to stop an installation:
    • via the Altair HyperWorks Product Installer (main installer) does not clean up the already installed files, but does clean up the files in the TMP/TEMP folder. You will need to uninstall/delete the installed files from the chosen install folder manually if Cancel was clicked.
    • causes the Add/Remove uninstaller icon to possibly not function correctly, and then manual removal of the installed files would be necessary.
  • The HyperWorks installers do not support the use of the default InstallAnywhere files. It is requested that a unique name is used when using a response file; for example,, and to use it with the -f <path_to_file>/<filename> command line option.
  • For NETSETUP client installs from a server installation of HyperWorks, a UNC path must be used to get to the server installation path through Windows Explorer or Windows Network.
  • On Linux, there is an issue with using the Altair HyperWorks Product Installer (main installer) with the IATEMPDIR variable to specify a custom temporary directory location. All sub-installers will try to use /tmp from the machine running the installers for temporary installer files.
  • With some versions of Gnome, there is a bug where the Linux icons are not placed in a hierarchy.
  • The installer does not run the Linux Menu installation by default, the user must run the installation script.
  • When the Main Uninstaller is used, desktop shortcuts, if any, will not be removed during uninstallation.

Resolved Issues

  • Hydra services started by Feko and Flux were not being stopped before an uninstall.
  • The installer names were being truncated on displays with scaling set to 125% or higher.
  • Installing Feko as a non-administrator no longer causes a non-fatal installation error.
  • Installing SimSolid by itself using the Altair HyperWorks Product installer (main installer) no longer causes a non-fatal installation error.
  • Installing Flux in silent mode on Linux no longer causes an unexpected terminal message.
  • HyperMesh File Preview (thumbnail) registration was not occurring for some types of installations.
  • Silent installs will no longer check for running processes using PowerShell.
  • When SimLab is uninstalled from a multi-product install, it no longer removes the common Python directory.

  • The most recent package was not selected in the Altair HyperWorks Product Installer (main installer) Choose Install Set panel in some cases.
  • Multiple successive spaces in the installation directory or shortcut folder caused an issue on Windows.
