In Upgrade Install, Which Version of Custom Action Will Be Used?
Hi,
I got confused when doing an upgrade install.
Say if I have a custom action CustomAction1 which is implemented in myCA.dll(stored in binary table). Then, I have a newer version of IS project and also CustomAction1 is updated with newer code in the new versioned myCA.dll.
Now I start an upgrade install, which version of custom action InstallShield or Windows Installer will choose?
Thanks.

When you are upgrading, the custom actions are executed from the project doing the upgrading (the new one). However, if you are doing a major upgrade, when the older version uninstalls, it will use the old msi to do that, so during the uninstall the older version of any custom action will run.

Thank you Kathy. This is great answer to me.
Though it would be great if InstallShield or Windows Installer can provide some documents on this.:rolleyes:
