We are doing an Installscript MSI project using Installshield 2009.
We have created a patch Design (Update.exe) using the same .ism file which is used for setup.exe and able to install successfully. But there is no seperate entry for patch in Add/Remove Program after patch installation. It is getting overwriiten with existing setup.exe installation entry in Add/Remove Program.
Our Requirement is to get the seperate entry for Patch in Add/Remove Program.
We followed as per the documentation to create patch under Patch Design.
1.Display Name Modified (Update) under Identification Tab.
2. Selected - Allow patch to be uninstall check box.
Can you please advice the way to get the seperate Patch entry in Add/Remove program after installing Patch?
It is not possible for a patch to be displayed in Add/Remove Programs for InstallScript MSI projects. This is caused by a limitation with the InstallScript MSI architecture.
Note that if an "embedded" InstallScript MSI is used, this limitation does not exist.
In InstallScript MSI projects, there is a setting in the General Information view (under the Project node) called InstallScript User Interface Type. By default, this is set to "Traditional Style (requires setup.exe)". If this setting is changed to "New Style (requires Windows Installer 4.5)" then the installation will use the embedded external UI support provided by MSI 4.5.
Note that using this option requires MSI 4.5 on a target machine to run correctly. It is highly recommended that a new project be created that plans on using this option. Also note that traditional style and new style (embedded) InstallScript MSI installations cannot be mixed: traditional style can only be used when upgrading or maintaining an existing traditional style installation, and the same applies to the new style.
