How to debug VS2010 setup project? I tried attaching to msiexec.exe , but it didn\'t help.
I am assuming you want to debug a custom action in the installer. If so having the solution open while running the installer and have this line of code in one of the events.
System.Diagnostics.Debugger.Launch();
When prompted say yes to debug the installer and select the instance of Visual Studio with your project already loaded.
