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.

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?

Many thanks
- Shaun
