Uninstalling TwinCAT 3

Uninstall order

The TwinCAT 3 installation is modular and consists of a series of component-based setups that are executed one after the other during the installation.

If you want to remove TwinCAT 3 completely from a computer, the following procedure is recommended.

Windows Control Panel > Programs and Features is open.
1. Uninstall all TwinCAT 3 functions. This step should be done before uninstalling TwinCAT, because some functions unregister with TwinCAT during uninstallation. If TwinCAT is no longer available, the uninstallation aborts with an error message.
2. Uninstall all TwinCAT component setups (e.g. TwinCAT Scope, TwinCAT Target Browser, TwinCAT Block Diagram).
3. Uninstall TwinCAT.

Uninstallation of the Visual Studio® Shell

A Microsoft Visual Studio® 2010 Shell installed by TwinCAT must be uninstalled separately if you do not want to keep it on your system.

Uninstall TwinCAT 3

All components of TwinCAT 3 can be simply uninstalled using the standard Windows functions provided for this purpose; no separate uninstall program is required.

Alternatively, you can run the installation program again. The program recognises that TwinCAT 3 is already installed and offers you the option of modifing (Modify option), repairing (Repair option) or removing (Remove option) the existing installation.
