Because it requires loading other users' registry hives, MSI doesn't support "cross-context" upgrades. So a per-machine install can't detect upgrade a per-user install. MsiEnumRelatedProducts likely uses the same logic. > I tried using MsiGetProductInfo and getting the "ALLUSERS" property > but apparently this isn't always set...at least it was not present for > our product. If it's not set, that means it's a per-user install. In fact, it's the only way of specifying a per-user install for a user with admin rights. Did you use INSTALLPROPERTY_ASSIGNMENTTYPE? That should ignore the tri-state ALLUSERS mess. > I know InstallShield uses a custom action called ISSetAllUsers that > does exactly this.
