Minecraft under El Capitan will only launch for one user.

I did the re install fix in order to launch minecraft under OS X 10.11 and indeed it works for the current user but if you log in as a second user (my daughter for example) then you get a different error message at launch telling you that you are running minecraft from the dmg file. Which I am not. Minecraft was moved to the Applications folder.
If I re install from dmg for this user and log back in to the original user, I get the same error.
So minecraft can only be launched from one user. In order to make it work, I need to erase it from the App folder and re drag it from the dmg.
Not too fun.
