# Select Package Combinations

This dialog displays in case new package VRCs are created during the installation process and these new package VRCs must be linked to an existing package combination. There are two scenario’s in which an existing package combination is extended in this way:

- A new package has been added to an already existing, released product. During installation a package VRC will be created for the new package. The new package VRC will be linked to the selected package combination.
- An add-on product is being installed in an existing environment. The new package VRC created for the add-on product must be linked to an existing package combination.
