Chapter 1: Installation Prerequisites for Windows

This document describes the prerequisite steps necessary to correctly install and configure all Ansys, Inc. products on Windows platforms for Release 2025 R1. To view a complete list of the products available, see Applications Included with Each Product.

Note:  Ansys Workbench is installed by default as product components to most Ansys, Inc. products. Ansys Workbench is not installed as part of the products under Ansys Additional Tools, nor with the CFD-Post only option. Ansys Workbench includes the following applications:

  • The Mechanical application

  • DesignModeler

  • DesignXplorer

  • Meshing

  • Remote Solve Manager

  • Fluent Meshing

  • EKM Client

  • GRANTA Selector

  • GRANTA MI

  • Minerva

  • SpaceClaim Direct Modeler

    Caution:  While SpaceClaim Direct Modeler and Ansys SpaceClaim can be installed on the same computer, only one of the applications can be configured with Ansys Workbench at any given time. Users can choose which version to configure via the CAD Configuration Manager utility.

  • SpaceClaim CATIA V5 Interface

  • ECAD

Because some of these applications can be run as standalone applications without Ansys Workbench, you will see some but not all of these listed separately as options when you uninstall. In such cases, you will need to select those options in order to uninstall those components.

Where supported, IGES and STEP Geometry Interfaces will be installed.

Some procedures apply only to specific products and are so noted.

Important Notice

If you want to run multiple releases of Ansys, Inc. software, you MUST install them chronologically (for example., Release 2024 R2 followed by Release 2025 R1). If you install an earlier release after installing Release 2025 R1, you will encounter licensing issues that may prevent you from running any products/releases. If you need to install an earlier release after you have already installed Release 2025 R1, you MUST uninstall Release 2025 R1, then re-install the releases in order.
