Cannot Delete a Constituent Address Linked to Registration

We are trying to delete a constituent's address. When we attempt to delete the address, we receive an error that it is linked to a registration. How do we delete the address?

When this error appears, it is most likely due to the fact that the address is still primary on an investment (registration) account. To rectify, go to the account referenced in the error. On that screen, click Address and then click Select a Different Address:

This will set the new address as the primary on the account. You can now return to the constituent record and delete the address.
