Oh yes

I often see users which still use old beta builds.

Yesterday we even had a quite skilled user mentioning "Hope I don't need to reinstall the software."

LOL

The process of installing the latest build is very simple.
You download the latest installer (the URL is always the same).
You run it and answer Yes or OK to all questions.
It takes very little time.

Try and time the whole process. I would be surprised if it takes more than a minute.
