Adding a script to new policy installs only

Is there a way to add a script to my default policy but only have it run on new installs? I have a script to install adobe reader but I only want to do that on new installs not on old assets in case they have full adobe installed.

In the policy, you can add a Set Up script that has “If never run” as its frequency and it will only ever run once on that asset.

You could also create a script that simply checks for Adobe Acrobat Pro, then only runs the reader installer if it’s not on the PC.
