The way I accomplished this was to store the install path in the
registry and then do a registry search to find out where the previous
version was installed. I believe the same thing could be accomplished
with a file search.
<Property Id="DIRFOO">
<RegistrySearch Id="FooPath" Type="directory" Root="HKLM"
Key="SOFTWARE\Acme\Foo" Name="Install Path"></RegistrySearch>
</Property>
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="DIRFOO" Name="foo">
<Component Id="FooPath"
Guid="C4F13748-9DA4-4e5d-8128-3AAC5EF25F7E">
<RegistryKey Root="HKLM" Key="SOFTWARE\Acme\Foo"
Action="createAndRemoveOnUninstall">
<RegistryValue Type="string"
Name="Install Path" Value="[DIRFOO]"></RegistryValue>
</RegistryKey>
</Component>
</Directory>
</Directory>

Subject: [WiX-users] How to find the installed path for update
Hi Wix-users,
I have developed a wix installer. It is an updatable installation
package. For the path, I set the default path as
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="APPLICATIONFOLDER" Name="ViewPoint6">
It will show "D:\ViewPoint6" as the default in InstallDirDlg.wxs:
<Control Id="Folder" Type="PathEdit" X="20" Y="100" Width="320"
Height="18" Property="WIXUI_INSTALLDIR" Indirect="yes" />
<Property Id="WIXUI_INSTALLDIR" Value="APPLICATIONFOLDER" />
However, if I installed the software in the other path, like
d:\testinatll for the first time. When there is new version avalable, I
want to update it. The InstallDirDlg still shows the path as
"D:\ViewPoint6", instead of "d:\testinatll".
How can I get the path for the update installation and set it to
InstallDirDlg? Probably, I need to have to dialogs, one for new
installation, defaut path is "D:\ViewPoint6", the other one is update
dialog, the path should be set as installed path.
Best regards
Chunyan
