ZIP installtion vs. MSI installation...What's the difference?

Manual ZIP file extraction is the traditional method for Orbiter installation. Download the ZIP file, create an Orbiter folder, and extract the contents of the ZIP file into the folder. That's all, and you are ready to launch orbiter.exe. This method is non-intrusive (it doesn't change the registry or system resources), allows multiple copies of Orbiter on a single system, and can be uninstalled by simply deleting the Orbiter folder. The MSI (Microsoft installer) method installs Orbiter like a normal Windows application. Just run the MSI file to start the interactive installation process. This method will automatically create a desktop shortcut and start menu entry, including an uninstall option. This method is easy to use, but a bit more restrictive.
