Windows Installer Logging Options

When debugging an installation package you can use multiple logging parameters in order to create a log. This log will contain different information for each parameter you use:

msiexec.exe [/i][/x] <path_to_package> [/L{i|w|e|a|r|u|c|m|o|p|v|x+|!|*}][/log]
<path_to_log>

• /L - enable logging
  • i - include status messages
  • w - include non-fatal warnings
  • e - include all error messages
  • a - mention when an action is started
  • r - include action-specific records
  • u - include user requests
  • c - include the initial UI parameters
  • m - include out-of-memory or fatal exit information
  • o - include out-of-disk-space messages
  • p - include terminal properties
  • v - verbose output
  • x - include extra debugging information
  • + - append to an existing log file
  • ! - flush each line to the log
  • * - log all information, except for v and x options
• /log - the equivalent of /l*

Sample command line:

msiexec.exe /i "C:\Example.msi" /L*V "C:\package.log"
