Hi Martin, Did you change the Product ID and the version number? Both of those have to change to be called a major upgrade.
http://wix.sourceforge.net/manual-wix3/major_upgrade.htm shows how to integrate a major upgrade into your .WXS file.

It used to work fine during MajorUpgrade. Today I signed the MSI with code certificate and also added one Merge Module. However now my MSI file gets installed as a new product and does not upgrade the existing installation as it used to do. As usual I only changed ProductCode and CurrentVersion properties. Does digital signing or adding merge module makes the MSI look like a new product? What else could be the case?
