Dell EMC OpenManage Installation Guide — Microsoft Windows Version 9.3.1

Failed Updates

Apply the MSI patches and updates provided by vendors to the original vendor MSI packages provided. If you intentionally or accidentally repackage an MSI package, or make changes to it directly, patches and updates may fail. MSI packages must not be repackaged; doing so changes the feature structure and Globally Unique Identifier (GUID), which break any provided patches or updates. To make any changes to a vendor-provided MSI package, use a .mst transform file.

NOTE: : A GUID is 128-bit long, and the algorithm used to generate a GUID guarantees unique GUID. The product GUID uniquely identifies the application.
