Please consider to choose “C:\Program Files\TwinCAT” during installation of TwinCAT 3.1. If you have installed it already then please uninstall and re-install it with the changed path. Please use the custom installation for this. That will automatically protect the binaries such that they can only be modified by an administrator. Please mind that already installed projects underneath C:\TwinCAT need to be moved. It is recommended to perform a backup of the complete device before such action. For security reasons, please remove the former content of C:\TwinCAT at the end of this sequence. This will also prevent confusion.
