Windows Installer / MSI: DebugView for Windows

DebugView is an application that lets you monitor debug output on your local system, or any computer on the network that you can reach via TCP/IP. It is capable of displaying both kernel-mode and Win32 debug output, so you don’t need a debugger to catch the debug output your applications or device drivers generate, nor do you need to modify your applications or drivers to use non-standard debug output APIs.


To monitor MSI installation actions in real time:

  1. Create the Debug (reg_dword) registry entry under
    HKLM\SOFTWARE\Policies\Microsoft\Windows\Installer and set the data value to 00000002.
  2. Start DebugView, now Windows installer installations will write their Standard/Custom Actions and this will be displayed in DebugView.
