How to run a ".bat" file during installation? - batch-file

Question

In a Setup project the executable files such as ".exe , .dll , .js , .vbs" are acceptable but there is no way to run a .bat file in a Custom Action.
The question is how to run the *.bat files during installation?

Answer 1

Well, after much searching and trial and error I have solved this. I'm not sure if this is the best way, but it works.
Here's the scenario: I have an application I would like to deploy via a Visual Studio Setup project. In addition to my application files, I would like to create a subdirectory in the target directory that contains a batch (.bat) file. I would like this file to run at the end of the installation process.
Here's what you do:
Create a setup project and configure as you normally would, including the subdirectory in which you'll place your batch file (you can just place it in the Application Folder directly if you don't want it in a subdirectory).
In the "File System" view (right-click on the project in Solution Explorer->View->File System), add the batch file you want to execute and cmd.exe (C:\Windows\System32\cmd.exe)
Open the "Custom Actions" view (right-click on the project in Solution Explorer->View->Custom Actions)
Right-click on "Commit" and choose "Add Custom Action"
Navigate to and select cmd.exe.
Open the properties panel for the newly created custom action.
Delete /Commit from the Arguments property.
Enter: /c "[TARGETDIR]subdirectoryname\batchfile.bat" in the Arguments property, where subdirectoryname should be replaced by the name of your subdirectory (if you put the batch file in a subdirectory like I did... if you didn't, the value should be /c "[TARGETDIR]batchfile.bat") and batchfile.bat should be the filename of your batch file.
That's it. The batch file will now be executed once the rest of the installation process is completed.
Here's an example for the sake of clarity:
My batch file: blah.bat
My subdirectory: mydir
The value of the Arguments for my custom action targeting cmd.exe would then be
/c "[TARGETDIR]mydir\blah.bat"

One other way to reach the same result is put a .vbs file in custom actions that runs the correspondent .bat file.
The following code is the "RunRegisterComponents.vbs" I put in setup application folder. Of course I put [TARGETDIR] as .vbs parameter in Visual Studio property window.
dim WshShell
Set WshShell = CreateObject("WScript.Shell")
' Read the "CustomActionData" property holding the install directory.
dim programDir
programDir= property("CustomActionData")
' Make the batch full file name and parameter
commandString = chr(34) & programDir & "RegisterComponents.bat" & chr(34) & " " & chr(34) &
programDir& chr(34)
' Set the current directory
WshShell.CurrentDirectory = programDir
' Run batch.
ret = WshShell.Run (commandString, 0, 0)
That is as I set my custom actions:
I hope this can help you!

Check this article (article is deprecated), even though it is in VB.NET it applies to C# as well. The most important part is (translated to C#) creating a new Class Library, and adding a new Installer Class with the following content: As stated in the article you can then create a new custom action with a reference to your just created project.
override void Commit(IDictionary savedState)
{
base.Commit(savedState);
System.Diagnostics.Process.Start("myApp.bat","your bat arguments");
}
Now we are adding batch file to your installer project. Create a setup project and configure as you normally would, including the subdirectory in which you'll place your batch file (you can just place it in the Application Folder directly if you don't want it in a subdirectory).
In the "File System" view (right-click on the project in Solution Explorer->View->File System), add the batch file you want to execute.
Build the installer project.

If you are trying to run a batch file that have relative paths during the installation process, that will fail for sure. That's because the batch file will take into account the directory where the installer is running, and not where the files were being installed. Use installer builders that copies batch files into temporary directory.
