That sounds like a promising approach. I'll try that one too. Anyone know any downside of getting the old installdir that way?

Betreff: Re: [WiX-users] Preserving install directory on upgrade The issue to beware of is about per user/per machine. Your search is for a per machine install, which is fine if you know that the previous was per machine and this one is not per user, and cross context would not upgrade anyway. Maybe ideally there would be a registry search option that behaves somewhat like the Registry table, searching HKCU (for the CU) on a per user install and HKLM on a per machine install then you'd get the location appropriate for the context if there was a mixture or multiple per user installs. --------------- Phil Wilson On Fri, Apr 18, 2014 at 4:45 PM, Jeremy Farrell <jeremy.farr...@oracle.com> wrote: > Perhaps I'm missing something, or this just works by luck, but it seems to > work for me in WiX v2: > > <Upgrade Id='$(var.GuidUpgrade)'> > <UpgradeVersion MigrateFeatures='no' Property='UPGRADING' /> > </Upgrade> > <Property Id="OLDINSTALLDIR"> > <RegistrySearch Id="GetOldInstallDir" Type="raw" > Win64='$(var.Comp64)' > Root="HKLM" > > Key="Software\Microsoft\Windows\CurrentVersion\Uninstall\[UPGRADING]" > Name="InstallLocation" /> > </Property> > > If I'm living on borrowed time, I'd value an explanation. > > >> From: Phil Wilson [mailto:phildgwil...@gmail.com] >> Sent: Friday, April 18, 2014 6:56 PM >> >> There is a kind of built-in way, and that's to set the >> ARPINSTALLLOCATION property (with a type 51 set property CA) after >> you know the folder location.
