Well, spent the day creating a Win10 1803 install.
Much to my surprise, that after installing, it ran without issue with appVol running.
So i then applied the app Stack to a system, and it looked like all was good.
Issue now is, when clicking on it to run.....noting happens.
so i tried running it as admin.....
it gives me a window saying "This app has been blocked by your system administrator"
Which is not the case. There isn't any GPO that blocks this application.
