c# - ClickOnce application replace current installed fliles

With ClickOnce applications, is it possible to replace the current files or install in a different directory when creating a new version? Because the error I get is:

Unable to install this application because an application with the same identity is already installed. To install this application, either modify the manifest version for this application or uninstall the preexisting application.

As the error message says, there are two options.

First, you as a developer should modify the version number of the ClickOnce manifest. This is done at the ClickOnce tab of the project settings. Note that ClickOnce version has nothing in common with your assembly (assemblies) version.

Another option is to uninstall the application and unfortunately, this probably has to be done manually. You have to find the ClickOnce deployment folder (C:UsersusernameAppDataLocalApps2.0) and manually delete all folder contents. This can also be done by invoking the

command from the commandline.
