This is an adaptation of 8e80528453.
Original commit message:
The MSI install scope was set to the WiX default, which is per-user.
However, with UAC, it could not be installed by a standard user
because InstallPrivileges is elevated by default, hence the install
scope should be set to per-machine. Furthermore, the default install
path is a per-machine location and setting the system path requires
administrator privileges.
By changing the InstallScope to perMachine, Start Menu shortcuts are
placed in ProgramData and not the installing user's AppData folder,
making the shortcuts available to other users. This also fixes the
installation when AppData is a network folder.
The custom action is necessary to allow upgrades. Since a per-machine
MSI cannot upgrade an application installed per-user, the custom
action checks if there is going to be an upgrade to a previous
version installed per-user and sets the installation as per-user to
allow upgrading. Hence, the advantages of installing per-machine will
only apply in fresh installations.
Fixes joyent/node#5849
Fixes joyent/node#7629

The original commit was adapted to search all upgrade codes listed in
the upgrade table, as the current installer tries to upgrade from two
different upgrade codes.
