Ductsize Level Upgrade

This product will upgrade your Ductsize Equal Friction level license to the full Static Regain level. You may only purchase this product if you already have a license for Ductsize version 6, with the Equal Friction license level. We will check our records to be sure you already have an Equal Friction license for version 6 before we process your order.

This upgrade does not increase the number of single-user licenses. It supersedes your existing license with a higher capability license.
