Common Mistakes
1) Not right clicking the setup file and selecting Run as Administrator. Even Admin users can't skip this step.
2) Not extracting .zip installation packages before installing.
* Skipping these steps won’t always produce error messages during installation, but unfortunately can corrupt the install causing issues.
Written Instructions
Installing Ansys License Manager (Windows)
Important Info
- License Manager Overview & System Requirements (Highly Recommended!)
- The steps to install and upgrade the license manager software are the same. If upgrading, the existing license file (& option file if applicable) will remain and a license does not need to be installed unless you have received a newer license.
- A client cannot checkout a license from a server running a version older than the client software. In this case, the license server must be updated to the newest version.
- First, select the computer you will use as your license manager. Click HERE for help & system requirements.
-
Download Installation Files:
- First, Sign up for access to the the Customer Portal if you have not already done so.
- Login to the Ansys Customer Portal > select Downloads > Current Release > expand the Tools section
- Download the package called Ansys License Manager (~200MB).
-
Comprehensive Install (Optional)
If you are troubleshooting a difficult issue and have already reinstalled once, please do the following before proceeding:
-
Prepare the Installation Files
- Unzip the file:
- Right click the file > select Extract All. (If the setup file is run without unzipping the archive file first, the installation will appear to complete successfully, but the program will not function properly)
- Unzip the file:
-
Install the Software
- Once the file has been unzipped, right click the setup.exe file > Run as Administrator (DO NOT SKIP THIS STEP)
- Note - Be aware that the license manager will be stopped during the installation and clients will not be able to communicate with the license server during this time. The installation typically takes ~ 5min.
- Follow the prompts to complete the installation. Default values are recommended unless there is a specific reason that requires otherwise.
- Upon completing the installation, the License Management Center web page will open:
- Once the file has been unzipped, right click the setup.exe file > Run as Administrator (DO NOT SKIP THIS STEP)
-
For Brand New Installation/licenses
- Install your Ansys license file(s)
- Next, you must add firewall exceptions to your firewall in order for other client computers to communicate with your license server.
-
For Upgraded Installations
- The previously installed license file will remain in place. You can verify this by selecting View FlexNet Licenses.
- Verify that the license manager is running by selecting View Status/Start/Stop License Manager.
-
Communicate License Server Name to Your Users
- They will need to specify this server name in the client license settings.
- Send them these instructions as necessary
Installing Ansys Client Software (Windows)
Important
- Ansys Hardware Recommendations
- Installing a newer version of the client software does not remove older versions. All versions installed on a computer can be used simultaneously.
- If multiple versions of Ansys need to be installed, the most recent version must be installed last, otherwise Ansys will not work properly. If you need to install an older version and already have a newer version installed, reinstall the latest version after installing the older version(s).
-
Download Installation Files:
- First, Sign up for access to the the Customer Portal if you have not already done so.
- Login to the Ansys Customer Portal > select Downloads > Current Release
- Select your Download type (Primary Packages or ISO Images):
- Primary Packages: If you only need to install a single physics package, downloading the primary package (zip file) is normally easiest as the download is smaller.
- ISO Images: If you are installing multiple physics packages, we recommend downloading the ISO files because these files include all physics packages (excluding Electronics) which makes installation faster.
- Download the installation files of your choice.
- Delete
Comprehensive Install (Optional)
If you are troubleshooting a difficult issue and have already re-installed the software, please perform the following before proceeding. -
Prepare the Installation Files
- If you downloaded a Primary Package / Zip File:
- Unzip the file by right clicking it and selecting Extract All. (If the setup file is run without unzipping the file first, the installation will appear to complete successfully, but the program will not function properly)
- If you downloaded the ISO Images:
- Double click the Disc 1 ISO file. This will mount it as a virtual DVD drive in Windows 10.
- Browse to and Double click all other ISO files, this will mount them as an additional virtual DVD drive. (take note of the drive letter is used for each disk as this will be used later)
- If you downloaded a Primary Package / Zip File:
-
Install the Software
- Right click the setup.exe file found with your installation files and select Run as Administrator.
- When prompted, specify the name of the license server you will be using.
- Follow the installation wizard, selecting the software packages applicable to you.
- Allow the installation to complete. This normally takes anywhere from 10-30 min, depending on how many applications you are installing and the speed of the computer.
-
Specify a License Server
- Lastly, Specify a License Server to connect to if you did not do so during the installation wizard.
- If you can't checkout licenses see HOW TO - Test & Fix License Manager Connectivity Issues
