AFAIK, this concept of patching is supported (i do use major upgrade scenario with series of patches in my products; using msi 2.0 schema). Problem you've described is considered to be an msi 3.0 engine bug. It seems that just installing msi 3.1 will fix the problem. One more thing, you have to author "UpgradeImage" element properly in build-my-patch.wxs script: add new "TargetImage" element for every version of your product the resulting patch must apply to. Also, please consider a wix docs for "TargetProductCode" element, "AllowMajorVersionMismatches" attribute -- that information you may find useful. ------------------------------------------------------------------------- Using Tomcat but need to do more?
