Repercussions of Per-Machine vs. Per-User Installations
Windows Installer can install or upgrade a software product for all users of a computer (per-machine c ontext) or for a particular user (per-user context) based on the access privileges of the installing user. If the initial Version is installed per-machine then all subsequent Versions and Patches must be installed per-machine.
If you plan to deliver your software product updates using Just-In-Time upgrade, then the users who is running the application MUST have the rights to install those updates. So if they do not have the rights to install per-machine and the software is installed per-machine then when the update is attempted it will fail.
