Upgrade an application

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

To upgrade an application

Open Group Policy Software Installation.
In the details pane, right-click the new Windows Installer upgrade package (that is, not the package to be upgraded).
Click Properties, and then click the Upgrades tab.
Click Add to create or add to the list of packages that you want to upgrade with the new upgrade package.
In the Add Upgrade Package dialog box, under Choose a package from, do one of the following:
- Click Current Group Policy object (GPO).
- Click A specific GPO, click Browse, and then click the Group Policy object that you want to upgrade.
Review the list of packages under Package to upgrade, which lists all of the other packages that are assigned or published within the selected Group Policy object.
Click the package that you want to upgrade, and then do one of the following:
- To replace an application with a completely different application (perhaps an application from a different vendor), click Uninstall the existing package, then install the upgrade package.
- To install a newer version of the same product while retaining the user's application preferences, document type associations, and so on, click Package can upgrade over the existing package.
(Optional) To make the upgrade mandatory, on the Upgrades tab, select the Required upgrade for existing packages check box.

Notes

To complete this procedure, you must be logged on as a member of the Domain Administrators security group, the Enterprise Administrators security group, or the Group Policy Creator Owners security group.
Before you can perform this procedure, you must first assign or publish the upgrade package.
Depending on the Group Policy object, the list of packages under Package to upgrade might have zero or more entries.
If this is an upgrade under Computer Configuration in the Group Policy console tree, the Required upgrade for existing packages check box is selected and unavailable because packages can only be assigned to computers, not published.

Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
