In a multiple package transaction, a chainer is used to dynamically include packages in the transaction. If one or more of the packages do not install as expected, you can roll back the installation.<h4 class="sbody-h4">Embedded UI handler</h4>You can embed a custom user interface (UI) handler in the Windows Installer package. This makes a custom UI easier to integrate. You can also invoke an embedded UI handler from the <strong class="uiterm">Add or Remove Programs</strong> item in Control Panel. Or, you can invoke an embedded UI handler during a Windows Installer repair process.<h4 class="sbody-h4">Embedded chainer</h4>You can use the embedded chainer to add packages to a multiple package transaction. You can use an embedded chainer to enable installation events across multiple packages. For example, you can enable install-on-demand events, repair events, and uninstall events across multiple packages.<h4 class="sbody-h4">Update supersedence resiliency</h4>This feature lets you correct for changes in the FeatureComponent table during supersedence.<h4 class="sbody-h4">Shared component patching resiliency during uninstall</h4>This feature makes sure that the most recent version of a component is available to all products.<h4 class="sbody-h4">Custom action execution on update uninstall</h4>This feature lets an update add or change a custom action so that the custom action is called when an update is uninstalled.</div><br/></span></div></div></div><div class="faq-section" faq-section=""><div class="faq-panel"><div class="faq-panel-heading" faq-panel-heading=""><span class="link-expand-image"><span class="faq-chevron win-icon win-icon-ChevronUpSmall"></span></span><span class="bold btn-link link-expand-text"><span class="bold btn-link">Issues that are addressed in Windows Installer 4.5</span></span></div><div class="faq-panel-body" faq-panel-body=""><span><div class="kb-collapsible kb-collapsible-collapsed">The issues present in earlier versions of Windows Installer that are addressed in Windows Installer 4.5 are as follows:<ul class="sbody-free_list"><li>The SeBackupPrivilege user right was missing in the Windows Installer service.
