Hi @sunsharm, Thank you for your post. Could you please provide a screenshot of your Help > About InstallShield screen from your copy of InstallShield that you are using to configure the affected project via private message? This allows me to match the InstallShield service pack level and edition. Which project type are you using? Basic MSI? InstallScript? Or InstallScript MSI? The project type should be indicated in square brackets on the InstallShield title bar when your affected project is open: [<Project Type>] Are you configuring a minor upgrade which installs the newer version over and on top of the previous version without a prior uninstall? Or are you configuring a major upgrade which automatically uninstalls the previous version then installs the newer version? Please let us know if you have any questions or concerns. Thanks! ...
