How do I extract MSI files?

How can I extract MSI files? I need to extract the contents and apply an update... I have no idea on how to do this.
 
You'll need something that can actually produce MSI files, such as Wise for Windows Installer, InstallShield Developer, etc.
 
Unlike many other installation files, MSI is not just a collection of compressed files.

MSI files are actually little databases laid out in a structured storage file.

As a result, depending on how it was organized together, extracting individual files might vary from the impossible to a very complicated affair.

To patch an MSI you should have been given an MSP file. You can't extract an MSI file and update one of the files without an MSI editor like wise or installshield.
