I tried nearly all solutions list on page How to implement WiX installer upgrade? , but didn’t upgrade successful. always prompt this message when I was upgrade:
“Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel.”
When I trace the installer log, it shows:
Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel.

Any configuration I missed?
To make a package perform a major upgrade you must increase its ProductVersion and change the ProductCode.
