If you are using the MacUpdate Desktop app to update the software on your computer please be careful: DEVONthink Pro and Pro Office are using the same “Bundle ID” to make both of them compatible to e.g. the same scripts and Automator actions. Unfortunately MacUpdate Desktop is using the Bundle ID for identifying updates. So it can happen that it, out of confusion, updates a DEVONthink Pro to a Pro Office or vice versa which then of course, asks for a proper license code.
We will change our approach here with a future version but we cannot do this for the current versions as it would break proper scriptability for many.
So if you are using MacUpdate Desktop please exclude DEVONthink Pro or Pro Office from the tracked applications and let it update itself using the built-in update function.
