The silent uninstallers allow you to automate these tasks from another batch/script file. The silent uninstallers are available on Windows and Linux.
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 installers. You may want to delete any remaining directories and files manually.
You should create a backup of any files you wish to keep, such as your SIMULIA license file (typically named abaquslm.lic or simulialm.lic) and the FLEXnet licensing server debug log file (typically named simulialm.log).
