My understanding is that QFE2 is created as the difference between the RTM and your current code base. Applying QFE2 will use RTM as the base whether you installed QFE1 or no. There should be no need to uninstall QFE1 short of wanting to prevent user from ever running that code (which would be the case if user uninstalls QFE2 and has QFE1 installed before that).

Subject: [WiX-users] recommended way to uninstall previous small updates Hi, I am using windows update to release the small updates (QFEs) after V1 RTM. Suppose I have QFE1 (released earlier) and QFE2 (released later). QFE1 should be uninstalled before QFE2 is installed so that any new QFE can use the RTM image as base. What is the recommended way to uninstall QFE1? Should I add a custom action in QFE2 to detect and uninstall previous QFEs? Or I don't need to do anything and windows installer is smart enough to uninstall QFE1 before it installs QFE2? Or I can author some pre-processing commands in windows update to detect and uninstall QFE1, then install QFE2? Appreciate your guidance.
