Thanks, what I did is same as what you suggested. The difference is yours CA has condition but mine is setting the INSTALLDIR property immediately. I checked some sample code of Wix, and found that some of them do not use registry to store install path and can also get user specified path when uninstalling. How can I do that? I am seeking a way not using registry.

You probably want the directory tree to look like this: > <Directory Id="TARGETDIR" Name="SourceDir"> > <Directory Id="ProgramFilesFolder" Name="Program Files"> > <Directory Id="MyAppFolder" Name="myappname"> > <Directory Id="INSTALLDIR /> > </Directory> > </Directory> > </Directory> This sets INSTALLDIR to be (by default) Program Files\myappname. You shouldn't have to do anything special to uninstall the application. I write INSTALLDIR to the registry to store the path for use later (i.e. during upgrades, instead of using the default directory, it remembers their preference). My INSTALLDIR registry stuff looks like this: <!-- Existing install path --> <Property Id="EXISTINGINSTALLDIR" Secure="yes"> <RegistrySearch Id="Locate_EXISTINGINSTALLDIR" Root="HKLM" Key="SOFTWARE\Company\Product" Name="InstallPath" Type="directory" /> </Property> <!-- custom action specification --> <CustomAction Id="Set_INSTALLDIR" Execute="firstSequence" Property="INSTALLDIR" Value="[EXISTINGINSTALLDIR]" /> <InstallExecuteSequence> ... <Custom Action="Set_INSTALLDIR" After="FileCost"><![CDATA[NOT Installed AND (NOT INSTALLDIR) AND EXISTINGINSTALLDIR]]></Custom> ... </InstallExecuteSequence> <InstallUISequence> ... <Custom Action="Set_INSTALLDIR" After="FileCost"><![CDATA[NOT Installed AND (NOT INSTALLDIR) AND EXISTINGINSTALLDIR]]></Custom> ... </InstallUISequence> -kevin On Nov 24, 2008, at 9:23 AM, [EMAIL PROTECTED] wrote: > Date: Mon, 24 Nov 2008 21:25:05 +0800 > From: "Jianjun An (Person Consulting)" <[EMAIL PROTECTED]> > Subject: [WiX-users] How can I get the correct INSTALLDIR at the > beginning of uninstall? > To: "wix-users@lists.sourceforge.net" > <wix-users@lists.sourceforge.net> > Message-ID: > <[EMAIL PROTECTED] > > > > Content-Type: text/plain; charset="us-ascii" > > Hi: > > I wrote a MSI file to install my application.
