Multiple installations of same application

[smpmartins]

Hi.
I have applications that can have multiple instances of it installed on the same machine.
I use an InstallScript MSI Project to generate my setup.
My problem is when I try to execute the setup in a machine that already has the application installed. In this case the maintenance setup is launch instead of the new instance setup.
How can I set my setup to always install my application?
Thanks in advance.
Best regard's,

Hi,

The Multi-Instance support is only available in Basic MSI project types and Pure InstallScript Project type. You will have to change the project type to either of the above two.

Thanks,
