If I create a GPO for Adobe Acrobat, version 7 and deploy it to all the workstations. At a later time, I want to install Acrobat 7.0.5 --- If I change the MSI file that the GPO points to, will Group Policy re-apply the new version of Acrobat. What I am bascially asking, what is the best practice for creating a GPO and having it re-deploy if there are updates to the app?
