Thread: How to selectively upgrade part of features of my program?

    Question How to selectively upgrade part of features of my program?

    My program has several components which are independent of each other, so different components may have different versions. So when I publish a new version of my program, I hope that user can selectively upgrade just part of components, with rest components staying the old version. However, when I use the feature dialogs, those unselected features will be uninstalled, which is not what I expected. So I want to ask whether there is a way to selectively upgrade part of features? Do I need to write a custom dialog to implement this requirement?

    So your application exists in your installer project out of different components.

    Lets say:
    comp A - version 1.2.0
    com B - version 1.6.0
    comp C - version 1.5.0

    form application v1.8

    so when you release application v3.0 with
    comp A - version 2.8.0
    comp B - version 2.5.0
    comp C - version 2.4.6

    you can end up with application 3.0 with comp A V2, comp B V1 and comp C V2???

    How do you test this as you have several different possibilities?

    Personally I think this is not a good approach.
