Solved! It seems that (an older version) of Canon Easy Web-Print EX which shipped with the (in our case) Pixma MG8120 was putting its Uninstall values directly beneath the Uninstall key instead of in its own product-specific key and didn't clear them on uninstall.
So for a new install of our product, [PREVIOUSVERSIONSINSTALLED] resolved to an empty string thus causing my AppSearch to resolve to HKLM:Software\Microsoft\Windows\CurrentVersion\Uninstall\@InstallLocatio n where it happily found the erroneous InstallLocation value. The current version of the Canon software on their web site creates the correct Uninstall key/value hierarchy so I was unable to reproduce it on my machine. These people ran into the same issue but were unable to figure it out.. http://community.mediabrowser.tv/permalinks/2650/cronos-install-error Is there any way to get AppSearch to log what path it is searching or at what path it found a valid value? That would have helped tremendously in this case. -----Original Message----- From: Arnette, Bill [mailto:bi...@signalscape.com] Sent: Wednesday, February 13, 2013 11:42 AM To: wix-users@lists.sourceforge.net Subject: [WiX-users] RegistrySearch returning strange value Hi all, I ran into the strangest problem on a customer's machine today. He was installing a new version (MAJOR upgrade) of our software which has the authoring below. We set INSTALLDIR from UPGRADEDIR if a previous version is installed (SetUpgradeInstallDir custom action) and make the installation folder read-only (conditioned on UPGRADEDIR<>"") on the [Admin]FolderForm to force the new version to be installed to the same location. On this particular customer's computer, UPGRADEDIR was set to some other application (in fact a Canon software component). This would happen even if I uninstalled the older version of my application and the Canon software. My first thought was that for some reason our UpgradeCode was the same as the Canon software; though we should be able to have GUID collision like that. But after downloading and examining the Canon software's installer, it does not even appear to be Windows Installer based. I am going to modify the conditions to also require PREVIOUSVERSIONSINSTALLED to be non-NULL to determine that this is an upgrade, but why would the RegistrySearch return some other application's Uninstall key? WiX version is 3.0. Installation target is Win7 64-bit. Application/installer is 32-bit. Thanks in advance for any insight you can provide.
