Locating log files on Windows computers

When the installation utility finishes installing products or creating an installable image, it displays a status message indicating the success or failure of the process. The page also contains a link, View Log, to the concatenated log file and displays the log file's location and name. The log file's name is determined at run time and contains the name of the computer on which the installation utility was run and an incremental time stamp. 

All log files are deleted after the installation is complete, except for the concatenated log file, unless:

  • You started the installation utility and used the -trace command line option or the -createcontrolfile command line option
  • The installation failed with an out-of-space error

The installation utility stores the log files at %APPDATA%\BMCinstall

By default, the Application Data directory on Windows operating systems is hidden. To view this directory so that you can locate the installation log files, open Windows Explorer and for Windows NT, select View > Options > Show all files. For Windows 2000, Windows XP, and later, select Tools > Folder Options > View > Show hidden files and folders.

The following table provides the information log files that are created by the installation utility.

Log fileDescription
Concatenated logContains information from all other log files created during a product installation.
User logLists error messages about fatal errors that caused an installation to fail. The information in this log file is the first section in the concatenated log file.
Product logLists nonfatal error messages and post-installation information messages, such as whether a reboot is required after the installation is complete. The information in this log file is the second section in the concatenated log file.
Standard output logLists messages that are usually sent to standard output. The information in this log file is the third section in the concatenated log file.
Comprehensive or main logLists all actions performed by the installation utility during a product installation such as the products that were installed or added to an image, files that were copied or removed, registry entries made, and any version checking that was performed. The information in this log file is the fourth section in the concatenated log file.
Front end trace log

Shows detailed information about activities in the installation utility interface during installation. This file is created if you launch the installation utility from a command line and use the -trace command line option. The information in this log file is the fifth section in the concatenated log file. For more details on using the -trace command line option, see  Running the installation utility on Windows from a command line.
