I think I need help with setting up a package to first scan for a registry key and then to stop the deployment if the key is found. I need the package to run on computers that have a Firefox version OLDER than 15 (we have a handful of users that need to use an older version).
Initially I created a dynamic collection within Inventory, and then told the package to exclude any within that collection, but I found that some of the computers were not in the collection because they hadn't been scanned recently enough. So, I added the 'Scan' step as a pre-step to a PDQ Firefox package, and setting the registry key under the conditions tab "Does Not Exist". But I think I'm actually excluding the computer from being scanned, not from the package running, as users are getting this that shouldn't.
I'm clearly misunderstanding how to use this step, but I really need to get this package to scan and then eliminate based on the presence of a registry key. Any help would be greatly appreciated!
