I looked it up really fast: RemoveRegistryKey/removeOnUninstall creates an entry in the Registry table with the Name column being set to "-", which causes the key to be removed when the component is removed without creating the key when the component is installed.
The condition isn't part of the Registry table, it is a part of the Component table, and component conditions are not used when the feature containing the component is removed. Uninstallation of a component during upgrade is controlled the combination of two factors: the presence of the same Component-GUID in the upgrading package, and the sequence of the RemoveExistingProducts. If RemoveExistingProducts is sequenced early, the component will be removed every upgrade. If the same GUID isn't in the new package, the component will be removed every upgrade. You have to place RemoveExistingProducts "late" (either right before or after InstallFinalize). Note that using the "late" placement of RemoveExistingProducts requires a more strict observance of the component rules. -----Original Message----- From: Sebastiaan Deckers [mailto:c...@pandion.im] Sent: Friday, February 12, 2010 2:11 PM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] Selectively uninstalling components during major upgrade Thanks for the tip. Unfortunately the registry keys still seem to get deleted during the upgrade. I'm using a RemoveRegistryKey/removeOnUninstall with the "NOT UPGRADINGPRODUCTCODE" Condition. My guess is that the Condition gets evaluated at installation time instead of during the upgrade. Is that how it works? Then how can I delete these registry keys only during a manual uninstall, while leaving them intact during an upgrade?
