I need to know if Windows installer allows changing a merge module destination on minor upgrade (patch). I am working with a basic MSI project which contains a merge module with wrong target path.
I don't think you are allowed to change the destination path of any component when performing a minor upgrade. You would be able to install the files to the new destination, but the ones that were previously installed would be left behind, which would mean that the RemoveFile table must be used. If I were you, I would rather go for a major upgrade. Check here: http://helpnet.installshield.com/installshield18helplib/MajorMinorSmall.htm
