Sometimes you want to create a collection that will find all the computers that don't have a particular software installed and push it to it. This is a good dynamic way to use SMS instead of direct computer addition.
Assuming you have Adobe Reader setup to install to all computers you can key this off of the Workstation collection or all computers if you wish. You notice that I use the "LIKE" condition instead of the "equals." I do this because you never know what version you might have. Look at Reader 7.09, even though you update your package with the latest reader you would need to change the collection. This way it will always look for the computers with no reader. This is assuming of course, that you push the updates to reader and not uninstal and reinstall the whole application each time.
