We talked more in-depth about this in our article titled "Do not delete your Windows Installer folder". If you place your files into the Application Data or Local Application Data folders and then delete the source MSI during the repair or self-healing process , the Windows Installer will ask you for the location of the source media. To avoid this from happening, the IT Pros community reached a common workaround that you can implement in the MSI - let's see what it is.
So, instead of placing the files in the Application Data or Local Application Data folders, you would use the install directory. To do this, perform the following steps:. Parameters "version" ; Step 5: Configuring automatic upgrades of new builds Often we want to upgrade an old installed application with a new one in the user's systems and this should happen using the new setup file which we will distribute to users.
That means the new installer file should automatically delete old files and upgrade new files. This is done by setting a few properties in the setup project as follows: Remove the Previous version: It should be true to remove the previous version of your application. Detect Newer Installed: Version should be true. Version : will be changed whenever you want to make a new build. With the change of version, studio will ask you to change product code and you should click yes.
Upgrade Code : This should not be changed since it's common for all builds and. Net uses this code to detect old builds. With this, your setup should work and remove any older versions of applications. Although it is some times problematic particularly in Windows 7 where setup doesn't behave as expected, So additionally I tried to change the version for each project in my solution, and it worked for me.

I have created a custom demo installer and DLL attached with this article. I am also providing detail description about the creation of this demo installer along with images. A dialog will appear as shown below. In this dialog, we have to select project type. Since our task is to create installer, we have to select " Setup and Deployment " under " Other Project Types ".
We have to provide installer project name. I had provided project name as " CusomtActionInstaller " as shown below:. After clicking " OK ", Installer project will get created. It shows file view of the installer which contains " Application Folder "," User's Desktop " and " user's program menu ".
All the files which are required by the application are added in this folder. It will open a browse dialog which can be used for selecting required application files.
