Thanks, Phil. My impression that ARPSYSTEMCOMPONENT told the MSIEXEC not to write any ARP registry entries came from an MSDN blog from some 6 years ago:
http://blogs.msdn.com/b/heaths/archive/2005/08/05/448198.aspx So the information may not be correct. Ultimately I'm looking to see if use of ARPSYSTEMCOMPONENT is the appropriate practice to suppress the MSI creating an ARP entry when using Burn (which also creates an ARP entry). Or is there another practice? The WiX installer itself doesn't use ARPSYSTEMCOMPONENT and doesn't suffer from a double-entry in ARP. I'm interested in the mechanism that it is using.

Subject: Re: [WiX-users] WiX Burn - Use of ARPSYSTEMCOMPONENT To Suppress MSI Files from Add/Remove Programs - Email found in subject ARPSYSTEMCOMPONENT is just a property you set in the property table of the MSI, like any other property. There's no need for anything special to set it. " As I understand this property of MSI files, it will prevent the installation from writing any registry entries for the MSI in Add/Remove Programs." No - it still writes the registry entries. It just means you won't see your MSI shown in Add/Remove Programs.

Subject: [WiX-users] WiX Burn - Use of ARPSYSTEMCOMPONENT To Suppress MSI Files from Add/Remove Programs With thanks to Tobias and Cody, I'm making progress on WiX Burn with a managed WPF UI. I've used WiX to create an MSI and Burn to create a bootstrapper for it. After installing with the bootstrapper, I have two entries in Add/Remove programs: one for the MSI, one for the bootstrapper. There have been some messages suggesting the use of ARPSYSTEMCOMPONENT in the MSI to suppress its appearance in ARP. As I understand this property of MSI files, it will prevent the installation from writing any registry entries for the MSI in Add/Remove Programs. But I don't see it in the WiX 3.6 MSI, which uses Burn + WPF for deployment. How does Burn suppress the MSI entry in ARP when installing WiX 3.6 and (most importantly) what is the "supported" or "official" or "recommended" way of suppressing MSI entries with our own Burn-based solutions?
