Can users with user-level privileges install managed applications?
Those with user-level privileges can install managed applications if the system administrator has enabled the installation. Otherwise, the user will only be able to install MSI applications provided the user has permission to write files, create directories, and write registry keys in the locations where the installation typically writes those resources. If the user cannot write to a location, then the installer will only be able to write to that location if the administrator has given permission for the installer to do so.
