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
