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.

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.
