TriCaster is not designed to be user-upgradable. For certain features to work correctly, specific versions of third-party utilities must be present. These applications are upgraded in timely fashion in official TriCaster updates.
It is quite likely that any attempt to update these manually will have unintended results, and you are strongly cautioned against doing so (unless otherwise directed by Customer Support).
