Da hell is going on with that application after DEMO version installed?!

Here is an existing thread about this topic, and they seem to have some sort of solution:

Application 'LCC2' has caused... error: Process with the ID NOT found

It works temporarily for the control centre but trying to load Halion SE into Ableton just returns the same error. So its currently unusable. Is this a bug or an issue with the latest Windows 10 update? It was working yesterday but not today and the only thing changed is that update.
