per-user

What happens if an MSI installation is set to install as per-user, and 3 different users log on and each install the app? Will Windows Installer recognise that the same MSI has already been installed into Program Files and therefore it doesn't need to install it again?

What happens if one of the 3 users then uninstalls the app while they are logged in? Will Windows Installer recognise that 2 other users still need the app to be installed and therefore leave alone the app folder in Program Files?
