Jenifer wrote: Hi, You would need to opt for Minor upgrade : A minor upgrade is a change to the product database and files large enough to merit a change to the ProductVersion property but not to the ProductCode property. In other words, both the package code and the product version number are different than those in the earlier installation package, but the product code of the minor upgrade does not change. An example is updating version 1.1 of a product to version 1.2. Minor upgrades usually do not have significant changes to the installation organization between versions. A minor upgrade packaged as a full installation acts like a first-time installation if an earlier version is not present, or it installs over an existing installation of a product. Essentially for an upgrade of an existing installation, a minor upgrade installs the differences between your version 1.2 and 1.1 application.

How to change the message in the pop-up from the upgrade -I hope it is generic message,custom message on upgrade might not be generic use-case. 3.Modify the entry in the specific xml of the installation path in the process-Do you mean by default installation path? Questions from your attached document: 4.Is it possible to change banner image-Yes.You can do this via dialog-editor.(Here it is InstallWelcome dialog) 5..Is it possible to change text been displayed during installation-I guess it comes from msi events.So it might be not possible to change those messages. Thanks, Jenifer Thank you Jenifer and Please one more help, I am changing the value of the entry at installation, like the xml below, but how can I prevent the value of the entry when I update? I want to designate two entries in Config and two entries in Patch [Features] so that they work during installation and update respectively.
