It is time to upgrade your QB Desktop Enterprise version to a newer one to run on Win Server 2019. You can purchase a new license thru select partners and you will get perpetual discounts on renewals. Another option, downgrade your file and you can still purchase QB Desktop 2024 Pro Plus or Premier Plus.
