Hi,
I have two questions.
1. How to determinate if a previous version of my program is already installed
2. How to findout what features was selected to be installed in the previous version.
Because if a previous version of the program is already installed I need to use registry settings set by that installation. Now when I upgrade, msi resets the registry entries, not good.
I use VBScript in my custom actions.
Regards
Simon G

You can add an entry to the Upgarde table to detect the previous version. Set the Migrate feature States bit to keep feature selection.
