MSIINSTANCEGUID property

The presence of the MSIINSTANCEGUID property indicates that a product code–changing transform is registered to the product. The value of the MSIINSTANCEGUID property specifies which instance of a product is to be used for installation. The MSIINSTANCEGUID property can only reference a product that has already been installed with an instance transform.

Instance transforms are product code–changing transforms available with the installer running on either Windows Server 2003 or Windows XP. For more information, see Installing Multiple Instances of Products and Patches.
