Re: [WiX-users] How to debug CustomAction DLL

[gapearce <mr_...@ya...>]

I found it pretty easy and straightforward using VS2008 to attach to a setup
program awaiting user input from a message box.  It was very easy...

This MSND article touches on it -
http://msdn.microsoft.com/en-us/library/aa368264%28VS.85%29.aspx - 

just attach to the process that has your messagebox title in it.  

add a breakpoint in VS2008 on the line of code in the dll after the
messagebox.  
Of course the code has to match the dll...

Respond to the button in the messagebox.  It will close and stop on the line
in the debugger.

You do have to remember to remove / disable the message boxes as stated
above...when you ship, or when they become so annoying that you can't take
it any more.
