Troubleshooting MSI Installation with msiexec.exe log

Unraveling the Mysterious Mysteries of MSI Installation with msiexec.exe Log

Is msiexec.exe log safe?

The msiexec.exe log is safe to use for troubleshooting MSI installations. It is a log file generated by the Windows Installer during the installation process and contains valuable information about the installation, including error messages, warnings, and exit information. By reviewing the log file, you can identify and resolve any issues that may have occurred during the installation. To enable logging, use the /L parameter followed by the desired logging options and the path to the log file. For example, msiexec.exe /i installer.msi /L*v example.log will create a log file named “example.log” in the specified location. By analyzing the log file, you can gain insights into the installation process and take appropriate actions to resolve any problems.

How to repair or remove msiexec.exe log

To repair or remove the msiexec.exe log, follow these steps:

1. Open the command prompt or PowerShell as an administrator.
2. Navigate to the location of the msiexec.exe file using the “cd” command.
3. To repair the log, use the command “msiexec.exe /fpecmsi installer.msi /L*v log.log“. This will generate a new log file with verbose information.
4. To remove the log, use the command “msiexec.exe /uninstall installer.msi /L*v log.log“. This will uninstall the MSI file and generate a log file.
5. Alternatively, you can use the Windows Installer UI to repair or remove the log. Open the MSI file, select the desired options, and click “Repair” or “Remove”.

Remember to replace “installer.msi” with the actual name of the MSI file you want to repair or remove. The “log.log” is the desired name for the log file, but you can choose a different name if needed.

Creating a log with msiexec.exe

To create a log with msiexec.exe, you can use the logging options provided by the command. Open a command prompt or PowerShell window and enter the following command:

msiexec.exe /i example.msi /L*V “C:\path\to\log.txt”

Replace “example.msi” with the name of your MSI file and “C:\path\to\log.txt” with the desired path and file name for the log. This command will start the installation in UI mode and generate a log file with verbose information.

If you encounter any issues during installation, refer to the log file for more details. It will contain messages, error messages, actions taken, and exit information. Use this log to troubleshoot and identify the cause of any installation problems.

Remember to adjust the logging command based on your specific needs, such as changing the logging mode or using different variations of the logging syntax. This log can be especially useful when dealing with Group Policy deployments, silent installs, or uninstalling an MSI file.
