Enable installation logs for MSI installer without any command line arguments

Solution 1:

One Line Logging How-to: Install Your.msi and create a verbose log file. More below.

msiexec.exe /i C:\Path\Your.msi /L*v C:\Your.log

From the MSI SDK: "You can enable verbose logging on the user's computer by using Command Line Options, the MsiLogging property, Logging policy, MsiEnableLog, and EnableLog method".

Short Answer: So add the property MsiLogging property to your MSI's Property Table and maybe use "vp" as value (without the quotes).

Hot Debugging Tip: Search for "value 3" in the log file to find errors as explained by Rob Mensching (Wix & Orca author). MSI log files can be overwhelming otherwise. See more on log-interpretation below (yellow section).

Burn: WiX Burn Bundles (setup.exe launchers) have their own logging constructs (beyond the MSI-specific logging described above). In other words MSI files have their logging, and setup.exe burn launchers have theirs.

Express Logging (Verbose): Simplest possible, verbose logging from cmd.exe.

msiexec.exe /i C:\Path\Your.msi /L*v C:\Your.log

Quick Parameter Explanation:

 /i = run install sequence 
 /L*v C:\Your.log = verbose logging at specified path

Debug Logging (Verbose): Advanced, slow logging for maximum details captured.

msiexec.exe /i C:\Path\Your.msi /L*vx! C:\Your.log

Quick Parameter Explanation:

 /i = run install sequence 
 /L*vx! C:\Your.log = verbose debug logging at specified path

 The x adds extra debugging information, and the ! disables the log buffer.
 This means there is no lost log if there are any crashes.

All MSI Packages - Global Logging (policy)

Yes, you enable logging globally on the machine by setting the appropriate registry key. Each MSI launched will then cause a log file with a temporary name to be created in the TEMP folder. Sort file list by change date to get the most recent one.

Registry Key & Value: The actual registry settings:

[HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer]
"Logging"="voicewarmup"
"Debug"=dword:00000007

How-To: Please see this FAQ-entry from installsite.org, section "Globally for all setups on a machine": http://www.installsite.org/pages/en/msifaq/a/1022.htm for the exact procedure.

Heads-Up (technical detail): This is a very technical problem that may have a bothersome and highly unexpected pragmatic effect. A side-effect of this global logging is that any Session objects you instantiate from a script using the MSI-API will also create a log file in the TEMP folder. This can cause hundreds of log files to be created in the TEMP folder if you iterate all packages and instantiate a session object. Also in the Event Log (a big system administrator no-no!). Very specific problem, but just pointing it out. A cleanup of the temp folder and Event Log "solves" the problem - or better yet - just avoid creation Session objects. Note that your deployment tool could instantiate session objects unexpectedly. Maybe check after enabling logging so you don't get this silly problem network-wide.

Package-Specific Logging

Apart from global settings and policies, you can customize the logging per package via properties or custom actions or just specify options and logging location via the msiexec.exe command line.

Command Line: In its simplest form: msiexec.exe /i C:\Path\Your.msi /L*v C:\Your.log. Documentation for the msiexec.exe command line (look at section for switch: /L)

Properties: You can set the MsiLogging property in each package to customize logging. The MSI property MsiLogFileLocation holds the path to the log file. Use this if you want to open the log after installation.

Custom Action: You could investigate the Installer.EnableLog method of the MSI-API to customize the logging behavior for a specific MSI from a custom action. More: Windows Installer Logging.

Solution 2:

To enable auto logging for MSI installer it needs to be edit with Orca to set an appropriate value for MsiLogging property. MSI is editable with Orca, the official MS tool for editing MSI packages.
MSI packages are not executable binaries but rather a Database with data defining the installation process. We can add the MsiLogging property with value v.
