If an installer stores a log of the installation process, where would I find that log?
If there is an installer that does not log the installation process, how can I make it do so?
Windows installer logs are usually kept in the temp folder, you can get to this by going to run or an explorer bar and type the location as
The default folder for this is:
To enable Windows Installer logging yourself, open the registry with Regedit.exe and create the following path and keys:
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:
"*" - 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.
Please note that the above is just for MSI files or setups that take advantage of the Windows Installer. Some others will also create log files either in the temp folder, their application directory or the root of the hard drive. There is no one answer fits all.
You can also have the installer write an installation log wherever you like, as needed, without modifying the registry. Run the installer
This will run the install script and write all logging info (verbose) to the file
The options for the /L flag are:
Although the Microsoft support page references Windows XP, I have confirmed that this works for Windows 7.
