Sorry for the slow response... Yes, it seems that was the dumb thing I'd done to myself. The annoying thing is I thought I had tried setting mutually exclusive conditions without success, but it worked fine today.
Thanks also to Palbinder Sandher who gave the same information.

You have to have all of your NewDialog (and SpawnDialog, if I recall correctly) entries have mutually-exclusive conditions for any given Dialog/Control combination. I think it's documented on MSDN as well, but not very well or clearly. -----Original Message----- From: Foster, Richard - PAL [mailto:richard.fos...@peektraffic.com] Sent: Wednesday, November 24, 2010 9:27 AM To: 'wix-users@lists.sourceforge.net' Subject: [WiX-users] Showing a dialog warning users they are upgrading. Greetings all, I am trying to modify an installation so it warns users (by displaying an additional dialog during the installation process) if the installation will perform a major upgrade. For some reason, Windows Installer is not behaving the way I expect, presumably because I've done something stupid somewhere. In the main WXS file, there is an Upgrade element, like the one shown here: <Upgrade Id="---deleted---"> <UpgradeVersion Maximum="$(var.Version)" Property="PREVIOUSVERSIONSINSTALLED" OnlyDetect="no" IncludeMaximum="no" /> </Upgrade> I have created a dialog, and tried to bind it into the user interface sequence as follows: <Publish Dialog="WelcomeDlg" Control="Next" Event="NewDialog" Value="UpgradeWarningDlg" Order="1">PREVIOUSVERSIONSINSTALLED</Publish> <Publish Dialog="WelcomeDlg" Control="Next" Event="NewDialog" Value="LicenseAgreementDlg" Order="2">1</Publish> I have confirmed, using the Windows Installer log file, that PREVIOUSVERSIONSINSTALLED does get set when an older version is present. Unfortunately the UI is still going directly to the LicenseAgreementDlg and is never showing the UpgradeWarningDlg. I imagine I'm doing something dumb... but so far I haven't found anything helpful in the list archives etc. Can anyone suggest what the problem is?
