2.5.1 Linux platforms

The following procedures explain how to remove Abaqus product releases or FLEXnet licensing from Linux platforms.

To remove Abaqus FLEXnet licensing:

This procedure must be performed on the license server host, and you must be logged in as root or the owner of the license server.

Before you can remove the license server and license files, you must terminate the license server using the FLEXnet Licensing utility lmdown (see “lmdown,” Section 3.6.2).
Create a backup of any files you wish to keep, such as your Abaqus license file (typically named abaquslm.lic or simulialm.lic) and the FLEXnet Licensing server debug log file (typically named simulialm.log).
Remove the files using the following procedure:
```
cd flex_install_dir
rm -rf License
```
Remove the license server restart command from the computer's system startup file. Contact your system administrator or platform vendor for information on the system startup file for your computer.

To remove the Abaqus products:

You can remove a release of Abaqus by deleting the installation directories and all subordinate files. Your user account must have permission to delete the Abaqus directories. You must delete the installation directories for both the Abaqus solvers and Abaqus/CAE.

Type the commands
```
cd solvers_install_dir
cd ../..
```
Change the permissions of the directories and files by entering the command
```
chmod -R 755 SimulationComputeServices
```
Remove the installed files by typing the command
```
rm -rf SimulationComputeServices
```

2.5.2 Windows platforms

You can use the Programs and Features control panel or the silent uninstaller batch files to remove Abaqus products or FLEXnet licensing. The silent uninstallers allow you to automate these tasks from another batch/script file. The silent uninstallers are available only on Windows platforms. You must have Windows Administrator privileges to uninstall Abaqus components.

The uninstallers may be unable to remove some files; for example, files that are open in another application. In addition, the uninstallers remove only directories and files that were written by the Abaqus installers. You may want to delete any remaining directories and files manually.
