You can optionally uninstall Tekla Structures versions that you no longer use to save space on the computer.

1. Go to the Windows Control Panel > Programs > Programs and Features.
2. Select a component, click Uninstall and follow the prompts. Follow this order:
   1. Uninstall the Tekla Structures environments.

      The environment .tsep packages are uninstalled and the environment files are removed.

      For more information about uninstalling .tsep packages, see Install .tsep packages.

   2. Uninstall the main Tekla Structures app.
   3. If installed, uninstall the offline help package.
   4. If needed, delete the additional files or extensions related to Tekla Structures manually from the installation folders.
3. If you no longer want to run any version of Tekla Structures on the computer, uninstall these components that are not version-specific:
   • The Tekla Warehouse service and content components.
   • If you have a legacy on-premises license:
     • The Tekla License Borrow Tool.

       Return a borrowed on-premises license before you uninstall the license borrowing tool.

     • The Tekla License Administration Tool.
     • The Tekla license server.

Follow these instructions if you want to permanently remove the on-premises license server from your computer.

1. Make sure that all borrowed licenses are returned.
2. Start the Tekla License Administration Tool app with administrator rights. This tool is installed together with the Tekla license server and you can find it through the Windows Start menu on the computer that is hosting your license server.
3. In the Tekla License Administration Tool dialog box, go to the Statistic tab and ensure that no one is using the licenses.
   

   Note:

   Before you deactivate licenses, ensure that the licenses are not in use or borrowed. The borrowed licenses must be returned before they can be deactivated.

4. If you have not activated the automatic server notifications (the Notify Server option in Tekla License Administration Tool), you need to stop the license server manually in LMTOOLS:
   1. Go to Tekla Licensing > LMTOOLS through the Start menu or Start screen, depending on your Windows operating system. Start LMTOOLS with administrator rights.
   2. On the Service/License File tab, ensure that Configuration using services and Tekla Licensing Service are selected.
   3. Go to the Start/Stop/Reread tab and click Stop Server.
5. In Tekla License Administration Tool, go to the Licenses tab.

   The Activated Licenses area lists the active licenses.

   

6. Select the Deactivate check box to select the license for deactivation.

   If you activated more than one license of the same type in one go, you cannot deactivate those licenses one by one, but you need to deactivate all of the licenses in one go.

7. The Deactivate button is activated, click it.
8. Go to the Windows Services snap-in and stop the Tekla Licensing Service.

   You can find the snap-in using the Windows start menu search.
