advanced installer upgrade without uninstall

So not sure how to prepare the condition if i detect that with that version feature B is not compatible to be in disabled state and files not to be added or copied. I see that files from feature b are installed I have attached some modifications to your example so you can check. Now, open the v2 project, see that for the FeatureB I added another. You can also use the 'OptionalFeatsDlg' dialog for features.īuild and run the package, choose 'FeatureB' and finish the installation. Now, in the 'Dialogs' page, you can see the 'ConfigureDlg' dialog added, so the user can choose which Feature to install. Open the v1 project, go to the 'Files and Folders' page and see the 2. This is happening due to the 'MigrateFeatureState' action, whose purpose is to take the state of the features from the old package and transfer that to the new package.Īttached is a sample project with v1 and v2 projects.

If you delete the 'OptionalFeatsDlg' or 'ConfigureDlg' dialog from the second version, the user can not change the features and will be updated only the Feature3 from the first version. When you install for example, in version 1 only Feature3, then in version 2 that is detected. hp?t=10740 but I have an error when adding upgrade action also not sure how to execute MsiQueryFeatureState ( i was also doing this on dialogs by Feature example)īy default, this is already implemented.

So not sure how to detect if the feature is installed in the previous version and how to disable a feature to be installed in a new version when doing an upgrade if ConfigureDlg is not shown, I was looking at this blog post. Users can choose to install feature One of feature Two or Feature Three when doing an upgrade I will need to detect which feature is installed and to run upgrade only on that feature.Īlso if I use to show only if on ConfigureDlg Not OLDPRODUTS when an old product is detected I can't choose which features to be upgraded maybe that is ok but the problem is what will happen if, for example, I have installed Only a feature one on this machine and then I try to upgrade I don't want other features to be installed I want only existing feature to be upgraded. I have succeeded to make an upgrade of my normal installer and restoring old config files and everything seems ok for now.īut now I have my other installer with features and also I will need to apply the same.
