SCCM provides SEVERAL client deployment/installation options, including:   

• Client push installation: This allows you to automatically install the client SOFTWARE on a computer, or on a group of COMPUTERS.
• Manual installation: This allows you to install the client software manually on computers using CCMSetup.exe.
• Group policy installation: This allows users to access the client software under Add or Remove Programs in the Control Panel and install it from there.
• Software update point-based installation: In the case of client software installed on a computer, the computer receives client policies from the site. The policy states the name and port of the software update-point SERVER from which one can obtain software updates.
• Logon script installation: The login script installation is similar to the manual installation. The /logon installation parameter can be specified for CCMSsetup.exe. Whenever a client version is already installed on a computer, this parameter PREVENTS its installation.
