SUMMARY

Windows includes a registry-activated logging service to help diagnose Windows Installer issues. This article describes how to enable this logging service.

Note The registry entry in this article is valid for all Windows operating systems.

MORE INFORMATION

Windows Installer can use logging to help assist in troubleshooting issues with installing software packages. This logging is enabled by adding keys and values to the registry. After the entries have been added and enabled, you can retry the problem installation and Windows Installer will track the progress and post it to the Temp folder. The new log's file name is random, but begins with the letters "Msi" and end with a .log extension. To locate the Temp folder location, type the following line at a command prompt:

cd %temp%
To have us enable or disable Windows Installer logging for you, go to the "Fix it for me" section. If you would rather enable Windows Installer logging yourself, go to the "Let me fix it myself" section.

Fix it for me

Note This wizard may be in English only; however, the automatic fix also works for other language versions of Windows.

Note If you are not on the computer that has the problem, you can save the automatic fix to a flash drive or to a CD, and then you can run it on the computer that has the problem.

Let me fix it myself

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

To enable Windows Installer logging

To enable Windows Installer logging yourself, open the registry with Regedit.exe and create the following path and keys:
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer

Reg_SZ: Logging
Value: voicewarmupx
The letters in the value field can be in any order. Each letter turns on a different logging mode. Each letter's actual function is as follows for MSI version 1.1:
v - Verbose output
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
x - Extra debugging information. The "x" flag is available only on Windows Server 2003 and later operating systems, and on the MSI redistributable version 3.0, and on later versions of the MSI redistributable.

"*" - Wildcard, log all information except for the v and the x option. To include the v and the x option, specify "/l*vx".
Note This should be used only for troubleshooting purposes and should not be left on because it will have adverse effects on system performance and disk space. Each time you use the Add/Remove Programs tool in Control Panel, a new Msi*.log file is created.

Enable Windows Installer logging with Group Policies

You can enable logging with Group Policies by editing the appropriate OU or Directory Group Policy. Under Group Policy, expand Computer Configuration, expand Administrative Templates, expand Windows Components, and then select Windows Installer.

Double-click Logging, and then click Enabled. In the Logging box, enter the options you want to log. The log file, Msi.log, appears in the Temp folder of the system volume.

For more information about MSI logging, please see Windows Help. To do so, search using the phrase "msi logging" and select "Managing options for computers through Group Policy".

Note The addition of the "x" flag is available natively on Windows Server 2003 and later operating systems, and on the MSI redistributable version 3.0, and on later versions of the MSI redistributable.
