Hi, I’ve been using install shield Express to build my Delphi program setup, and the product is already installed on the customer mashie I have made some updates and wonder if there is a way to produce another setup with the same product name to upgrade my product without uninstall the whole setup to keep the data saved. I tried to update the version of the same ism but it appears as a new program in the “Add Remove Programs” in “Control Panel” Can anyone help me please?
