Thanks, as always, Bob! I put in the feature request (https://sourceforge.net/tracker/?func=detail&aid=2814132&group_id=105970&atid=642717).
Using the registry key SOFTWARE\Microsoft\Windows Installer XML\<version> is sufficient. I guess anyone using a Product Id="*" really needs to plan a detection scheme. Recently someone on the list was asking if there were any best practices and this might be one. In fact, it might be a good thing to add to WiXCOP. :) >-----Original Message----- >From: Bob Arnson [mailto:b...@joyofsetup.com] >Sent: Thursday, June 25, 2009 8:24 AM >To: General discussion for Windows Installer XML toolset. >Subject: Re: [WiX-users] Detecting if WiX 3.0 is installed > >John Robbins wrote: >> WiX 3.0 uses a Product Id="*" to autogenerate a product ID.
