We built WPF app and are delivering MSI for our Enterprise customers. We were creating MSI with Setup Project in Visual Studio. Since our customers are deploying apps through their Admin/System account, MSI should be set to per-machine context. What I am doing is now is that I create MSI and user orca to set property ALLUSERS=1. However, it does not seem to be fully working as per-machine installation. Is there anything that I need to take care of?
