So applications go bad, corrupt, uncooperative, etc, etc. In the desktop world, that's just a fact of life, and it happens on managed and unmanaged systems. One of the usual fixes is to remove and re-install the application. In Mirage, that entails removing the application layer through the Mirage console, having the user reboot, and then installing the application layer through the Mirage console. Do you think we could get a RE-INSTALL button? One click and application layer would go through the multi-step process without administrator intervention.
Hello, I think "Enforce All Layers" will do this job also.
But this will really set everything back and not only one AppLayer.
So yes you are right a Reinstall Applayer will be fine.
