When I searched in Google, I found some one has the same problem as me. And the
suggested solution is to define a property using RegistrySearch. And also
define a registry with the install path [APPLICATIONFOLDER]. So that the
upgrade will only happen when the registry with path found.
I tried it as:
<Property Id="INSTALLDIR">
<RegistrySearch Id='ViewPointRegistry' Type='raw'
Root='HKCU' Key='Software\Microsoft\ViewPointUpgrade' Name='InstallDir'
/>
</Property>
<DirectoryRef Id="APPLICATIONFOLDER">
<Component Id="RegistryForUpgrade"
Guid="D555488C-C8E7-44eb-91EC-3750602A7599">
<Registry Id='ViewPointInstallDir' Root='HKCU'
Key='Software\Microsoft\ViewPointUpgrade'
Name='InstallDir' Action='write' Type='string'
Value='[APPLICATIONFOLDER]' />
</Component>
</DirectoryRef>
And call custom action as:
<Custom Action="UpgradeStopServices1" Before="InstallFiles">PREVIOUSFOUND
AND INSTALLDIR</Custom>
But I got warning when I compile it:
warning CNDL1080: The Registry element has been deprecated. Please use one of
the new elements which replaces its functionality: RegistryKey for creating
registry keys, RegistryValue for writing registry values, RemoveRegistryKey for
removing registry keys, and RemoveRegistryValue for removing registry values.
And when I install this version 2 installer msi, select PathB, the problem is
still there.
Is there something wrong in the Registry define? How to change it?

Betreff: [WiX-users] Upgrade and new install
Hi Wix-users,
I have developed one upgradable installer with Wix3. As I understand that main
upgrade is same as new install. My scenario is that my version
1 has been installed to PathA. And I have an upgraded version 2. If I install
version to to PathA, the old files are removed, the new files are installed.
Everything is fine. If I install version 2 to PathB, the new files are copied
to PathB, same as new install. It sounds good.
However, there are custom actions in my installer, named MyCA. MyCA should be
called only by upgrade. So if version 2 installed to PathA, MyCA in PathA will
be called. It is fine. But if version 2 is installed in PathB, MyCA in PathA
will still be called. It causes some problem for PathB install.
How can I make a condition to MyCA, so that it will only be called when the
upgraded version installed in it's path? If version 2 is installed in PathB,
discard MyCA in PathA, do it same as new install.
Best regards
Chunyan
