How can I make a major upgrade to an installation set (MSI) built with Wix install into the same folder as the original installation? The installation is correctly detected as an upgrade, but the directory selection screen is still shown and with the default value (not necessarily the current installation folder).
Do I have to do manual work like saving the installation folder in a registry key upon first installing and then read this key upon upgrade? If so, is there any example?
Or is there some easier way to achieve this in MSI / Wix?
As reference I paste in my current Wix file below:
