Nothing will happen, the open product will not be updated. So users apps will NOT be shut down if they are using them.
So I can get it to attempt to update several times a day without worrying it will break a users application then?
What happens if a user opens an application that is in the middle of being updated? Will it just refuse to open?
If the user tries to open it, I would expect the update to finish before they were able to open the app.
You can check what happened in the log.
Great stuff. Thank you.
