Philips SpeechExec - Revoking a License Key
To re-use a valid license key on a new machine/new installation, users simply need to ensure that any previous installation of SpeechExec has been closed using File > Exit, and then uninstalled from the PC (if required).
This ensures that the connection to the SpeechExec server has been properly closed. Failing to close the software properly keeps the server connection active and will show an error when installing the software on another PC.
