You would need to save it somewhere and read it on upgrade, Rob has an example here http://robmensching.com/blog/posts/2010/5/2/the-wix-toolsets-remember-property-pattern/

Subject: [WiX-users] Preserving install directory on upgrade Hi, I recently detected a problem within my installer package (No UI). I implemented it with major upgrade capability to easily install new versions. What I have realized now is, that during major upgrade I loose my previousely set install directory: This is my directory structure: <?xml version="1.0" encoding="UTF-8"?> <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi";> <Fragment> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFilesFolder"> <Directory Id="INSTALLDIR" Name="MyCompany"> <Directory Id="DIR_App" Name="MyApp"> <Directory Id="DIR_Base" Name="Base"> <Directory Id="DIR_Bin" Name="bin"/> <Directory Id="DIR_Dll" Name="dll"/> </Directory> </Directory> </Directory> </Directory> </Directory> </Fragment> </Wix> The initial installation is called with parameter: INSTALLDIR=C:\test This results as expected with my application being installed to c:\test. If I make now a new version of my installation and call it with no parameter, the previosu version is deleted and the new version is intalled. But now the new version is installed to the default directory "C:\Program Files\MyCompany\.." Is there some way to preserve the custom install directory, so that MSI remembers it? Or do I have to write the INSTALLDIR to the registry and get it from there during upgrade? kinf regards, Michael ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
