  <p><strong>Glytzhkof edit</strong>: To clarify, the question deals with when a component GUID should be changed for an MSI component. A component can change with aspects such as: changed destination path, addition or removal of files to/from the same component, addition of registry data etc... This causes problems with regards to the so called component referencing, i.e the <a href="http://helpnet.installshield.com/installshield21helplib/helplibrary/IHelpCompBPRules.htm" rel="noreferrer">best practice for creating components</a> in MSI.</p>
