Service Packs are self-contained packages or patches that are used to update specific files within a User Workspace Manager application without reinstalling the full application. Service packs can be applied more often and reduce the need for system restarts on your endpoints. Service packs are delivered as a Windows Installer patch (MSP) file and are often referred to as patch files.
In this section:
Service Packs can be installed or deployed using the same technology and techniques used when installing MSIs. Both Microsoft System Center and the Management Center 8 FR4 can deploy MSPs. If neither of these products are available, service packs can be installed using the command line interface.
For example, the command:
msiexec.exe /p EnvironmentManagerAgent64.msp
installs any files that have been amended as part of the patch for just Environment Manager 64 bit agent.
The following command installs the base version of the Environment Manager Agent (MSI) and the Environment Manager patch file (MSP) simultaneously:
msiexec.exe /i EnvironmentManagerAgent64.msi PATCH=c:\fullpath\EnvironmentManagerAgent64.msp
A base version must be installed before the patch file can be applied.
If the patch file contains driver or hook files that are currently in use on the machine the patch is being applied to, you are informed that a reboot is required. If you chose to continue, the system is restarted when the patch has been applied.
For information on installing and upgrading service packs using Management Center, see the User Workspace Manager help.
Installation Order and Dependencies
It is recommended that all components of a service pack are installed and that the PersonalizationServerXX.MSP is installed first. All other components have no required install order.
You can roll back or install service packs using either the Management Center (8 FR4 onwards) or the Windows Control Panel.
When you uninstall a service pack, the product reverts to the previous latest build - whether a service pack or base version.
With the exception of the Personalization Server component patch file (PersonalizationServerXX.msp) All agent and console service pack components can be uninstalled.
