I will test the MsiBreak method shortly and remove > the MessageBox calls completely for a cleaner code then. I gave the MsiBreak method a quick try, but I couldn't make it work. I have set MsiBreak as a system environment variable, restarted Windows Installer service, restarted the shell window from where I invoke msiexec calls to make sure the environment is updated. But it doesn't pop-up any prompt to attach debugger as advertised. I haven't installed the Debugging Tools for Windows, as I run Visual Studio elevated to debug processes. I haven't restarted my computer: restart of a working machine with stage set to debug something is a royal PITA: the libopenvpnmsica.dll has more than one custom property to debug, restarting each time to switch MsiBreak to a different custom action is not viable. Therefore, I'd prefer to keep own MessageBox() call in the beginning of each custom action. It works 100%. Adding PID to the message is an option. I personally never needed it. When running Visual Studio elevated, you press Ctrl+Alt+P, followed by "msi" keystrokes to focus on "msiexec.exe" processes, then observe the MessageBox()'s title (which is deliberately set to function name) in the "Title" column of the available process list. Way faster than searching process by PID. Anyway, I have extended the debug pop-up dialogs to be more informative and include PID. Patch follows...
