Hello all,
I just get an idea to make my app setup project have an ability to revert to the previous version. The reason is here. At first, in production side, the app is alive (installed). Then when my user request additional features, then I need to modify/ upgrade the existing app. If the updated app is failed to function properly, they got option to revert to the previous version. Normally what I do is in the following step: - Create an app project - Create setup project for it with check for newer version and auto remove previous version. - Install/deploy to the user PC - Update the app. - Rebuild the setup project. - Install/deploy to the user PC (it will remove the previous version) Then I need to add additional step. * User try the new version. * If gto prob. user can revert the installation to pervious version. This idea is just like you installing windows driver / windows update. You got option to return to the old driver / windows version. Thanks in advance. CallMeLaNN
