(http://support.microsoft.com/kb/256986/EN-US/ )Description of the Microsoft Windows Registry
This article describes the registry-activated logging service that Windows includes for diagnosis of issues that involve Windows Installer.
The registry entry in this article is valid for all Windows platforms.
Windows Installer uses logging to help you troubleshoot issues that may arise when you install software packages. After you enable logging, you can try the unsuccessful installation again. Windows Installer tracks the progress and posts the data to the Temp folder.
The file name of the new log varies, but the file name begins with the letters "Msi" and ends with a .log extension.
To find the location of the new log in the Temp folder, type cd %temp% at a command prompt, and then press ENTER.
Enable Windows Installer Logging by Adding Registry EntriesWARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\InstallerThe letters in the value field are the options that are available to use with Windows Installer logging. You can use the options in any order. Each option turns on a specific logging mode. For MSI version 1.1, the function of each option is as follows :
v - Verbose outputIt is recommended that you use this service only for troubleshooting. Leaving the service turned on creates a new Msi*.log file every time you use the Add/Remove Programs tool in Control Panel. This activity adversely affects system performance and disk space.
o - Out-of-disk-space messages
i - Status messages
c - Initial UI parameters
e - All error messages
w - Non-fatal warnings
a - Start up of actions
r - Action-specific records
m - Out-of-memory or fatal exit information
u - User requests
p - Terminal properties
+ - Append to existing file
! - Flush each line to the log
* - Wildcard, to log all information except for the v option. To include the v option, specify /l*v.
