The ```uninstaller`` string can be either the windows GUID (aka msi prodcut code) OR the URL to the msi file. Both options work to uninstall a msi installed software.
The instructions as-are do not actually work. The uninstaller flag takes the windows GUID of the msi product code. And the various ```install_flags``` and ```uninstall_flags``` do NOT need leading, or trailing spaces.
@twangboy can confirm this is a better example (also see salt issue #25778https://github.com/saltstack/salt/issues/25778)
