3. History And Motivation  Application installation is a high TCO item Deploying an application upgrade strikes fear into the heart of administrators Deploying an application upgrade strikes fear into the heart of administrators  Problems with existing installation technologies Poor user experience Poor user experience Poor admin experience Poor admin experience Destabilizing to the OS and other apps Destabilizing to the OS and other apps Poor development experience Poor development experience

4. Administrator Experience Today  Setup is a black box Administrators want to know what it will do to them Administrators want to know what it will do to them  No easy way to determine the state of a machine  Difficult to lockdown desktops  Broken uninstall Can only refcount files Can only refcount files Cannot identify clients of resources Cannot identify clients of resources

5. Setup Development Today  Developing setup is often an afterthought  No notion of sharing setup logic between developers or products  Difficult to update and maintain Script-based setups Script-based setups  Fragile
