LabVIEW packed project libraries are designed to make patching easier. Packed project libraries have an MSI-recognized version resource number, which you can use to more easily make partial updates to the test system. You can replace a packed project library with a newer version without changing the VI or the TestStand steps that call into the packed project library.

By default, the TestStand Deployment Utility automatically includes files that differ from the baseline deployment version of the file. You must compile all LabVIEW packed project libraries before you create a patch deployment to ensure that the deployment utility correctly identifies modified libraries to include in the patch deployment.
