Detect Property : ISFOUNDNEWERPRODUCTVERSIONĪny idea what should I do so that i can just uninstall the previous installed version if found and then continue to install new version in a single installation?Įxpand the tree for '+ Upgrade Windows Installer Setup' if it is not already expanded. Select this top tree item and view the settings. For me I completely uninstall the old setup before installing a new setup because there are some unversioned files that I find problematic with the second option. It is worth testing to see if it will work for you. You want to add a new entry here if it does not already exist. The default entry for Prevent downgrades is inserted when you create a new project and is ONLY for detecting a newer version. I have an entry for "NewUpgradeForCurrentProject" (note that the name is not important, it just helps me to identify it) Do not modify this entry, create a new one using a right click on the top of the tree and select option for a new major upgrade item. On the Common Tab select the option 'Products sharing my upgrade code'. NOTE: Never change your upgrade code for an active product. ![]() Only change your product code and product version and package code. You can specify a range of version numbers to include or select 'Any earlier version'.ĭouble check the advanced tab - these should be automatically set for you based on your settings on Common. Note that by default Maximum Version is set to ***ALL_VERSIONS***.
