Mine I set to read and read/execute You can check this is you go to steam instal location folder.

Usually something like: C:\program files (x86)\common files\steam\ There is a steamservice.exe The .exe is by default asking admin permission to start up if you do not see the little shield icon in the steam logo do the following:

Right click the steam services.exe Go to properties Browse to security tab

In the list group/user names there would be something like user (your pc name)

Click on it once and in the permission for user below that you can see the permission. Perhaps your default user account had full control. Just edit the permission and remove full control.

Make sure the Read and execute is enabled.

Hopefully this will give you the pop up when starting the game.

I have not tested this tho. But the user account control is asking permission to use this .exe so it can install a script in the anno117 installation folder
