Installation Instructions

You must be connected to UCI Campus Network using campus ethernet or VPN in order to install ANSYS.

If you are using campus Wi-Fi, you need to use UCI's VPN because OIT blocks many network ports.

1) Mount the ISO labeled ANSYS2021R1_WINX64_DISK1.

    • Right click on file, select "Mount"

2) Double click the setup.exe after mounting the ISO`

3) Click Install ANSYS Products from the menu that pops up

4) Scroll down and click "I AGREE" and then click NEXT >>

5) Select Install Directory or leave it as the default. Do not change the checked & unchecked boxes. Click Next >>

6) INPUT License Server info.

  • You must be connected to campus via UCI VPN.

  • If you are using campus Wi-Fi, you still need to use UCI's VPN because OIT blocks many network ports.

  • If you continue to experience error messages, look at your Windows Firewall, Advanced Settings, Inbound Rules.

      • Scroll through and look for any ANSYS software that might be blocked.

7) The software should select the products to be installed based on the license server so click Next >>

If you select additional products, they may not run because we are not licensed for them.

Contact Lisa Preble, if you require use of a package we are not licensed for.

8) Configure CAD

  • It's up to you if you want to configure those during installation or after.

9) Click Next to continue installation.

10) You will reach the following install screen. It will install until it requires the second iso and the enter path to the next media window pops up. Mount the second ISO named ANSYS2021R1_WINX64_DISK2 and click browse and find your mounted iso. Do this again for Disk 3.

11) Click exit and your ANSYS software should now be ready to be used.

Further configuration for ANSYS 2021

There are additional steps for ANSYS 2021R1. If you are receiving license errors, please do the following:

1) Create or edit the LSHOST Environment Variable as a System Variable and add license server IP address

2) Check the settings in the Licensing Client Settings Manager. This utility doesn't like special characters so use the IP address.

  • Click TEST to test connection

  • Click SAVE at the bottom

Firewall settings

There are significant firewall exceptions that need to be made in order for all applications within ANSYS to function.

  • The most common problem is consumer anti-virus software blocks ANSYS.

  • For HSSOE computer labs, I use the built-in Microsoft antivirus and firewall. Below is the ANSYS firewall exception list for the HSSOE labs.

  • For your research use, you may not need all of these exceptions.

  • What I do, is I click on all of the apps in ANSYS and add a program exception whenever I see that an app is blocked.

15) ANSYS Electronics Suite does not open

A recent Windows update (2/8/2021), Microsoft update KB4571756, results in one of the Windows functions (DescribePixelFormat) crashing on startup.

For versions 2018.0 and newer, please try setting the environment variable ANSYS_EM_DONOT_PRELOAD_3DDRIVER_DLL=1 to get around the problem.
