So called lite applications remove certain components from -- usually resource heavy - applications to reduce download time, storage requirements or features so that they are not installed with the application on the user system.
Well known examples for lite applications are Nero Lite or Adobe Reader Lite which remove -- mostly unneeded -- functionality from the installer to speed up the installation and remove what is considered as bloatware by many.
Note: Skype Lite is no longer available. You can still download Skype for Business though and use it to install Skype without components that you don't require.
The voice over IP client Skype is another example. It is a popular application that will install features on the system by default that are not needed by some users at the very list. This for instance includes plugins for web browsers.
There are two ways of achieving this. The first is by downloading a Skype 4 Lite installer which works similar to the main Skype client installation but with the benefit that several components have been removed from the installer so that they won't be installed on the system.
The second is by downloading Skype Business which comes as a msi file. This msi file can be run with parameters that block several components from being installed.
The components that will not be installed are the Skype plugins for web browsers like Firefox and Internet Explorer, the Skype Plugin Manager and Skype Toolbar. Autostart of Skype will be disabled and the generation of the Skype icon on the computer desktop will be blocked as well.
What are the benefits of this installation method? Skype will start up faster and overall performance during usage is improved.
You can download the custom installer for Skype on the Custom Installers homepage.
Download Skype Business from the Skype homepage to use the second method instead. This will download SkypeSetup.msi to the local computer. To install Skype without select components run the following command: (via MSFN Forum)
start /wait msiexec /i SkypeSetup.msi INSTALLLEVEL=1 STARTSKYPE=FALSE ALLUSERS=1 TRANSFORMS=:removeStartup.mst TRANSFORMS=:removeDesktopShortcut.mst /qr
The most important parameter is installlevel=1 which restricts the installation to the Skype client and not add-on components such as toolbars or browser plugins. The other parameters are pretty much self explanatory.
