Examples of components include single files, a group of related files, COM objects, registration, registry keys, shortcuts, resources, libraries grouped into a directory, or shared pieces of code such as MFC or DAO.<br \/>\nThe installer service installs or removes a component as a single coherent piece. It tracks every component by the respective component ID GUID specified in the ComponentId column of the Component table.<br \/>\nNote  Two components that share the same component ID are treated as multiple instances of the same component regardless of their actual content. Only a single instance of any component is installed on a user&#8217;s computer. Several features or applications may therefore share some components.<br \/>\nBecause components are commonly shared, the author of an installation package must follow strict rules when specifying the components of a feature or application. This is essential for the correct operation of the Windows Installer reference-counting mechanism. For more information, see Organizing Applications into Components.<br \/>\nIn brief, these rules are:<br \/>\n\u2022\tEach component must be stored in a single folder.<br \/>\n\u2022\tNo file, registry entry, shortcut, or other resources should ever be shipped as a member of more than one component. This applies across products, product versions, and companies.<br \/>\nRegards,<br \/>\nRajesh Kumar<br \/>\nTwitt me @ <a href=\"http:\/\/twitter.com\/RajeshKumarIn\" target=\"_blank\" rel=\"noopener\">twitter.com\/RajeshKumarIn<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>rajeshkumar created the topic: Windows Installer Components A component is a piece of the application or product to be installed.
