After performing an upgrade of Extender, receiving an error when launching Dynamics GP that says, “Message #24574 is missing.”
All 18.X versions of Extender use a customer account code to register the product. All the error message is indicating is that you have updated to a newer version and you need to register the newer version using the same account code previously used.
Open the Extender registration window (Tools – Extender – Register Extender) and click on the Save button to close it. When you click on the save button, Extender will connect to the eOne registration server and update the registered version to match what you have installed. You will no longer get the error after re-registering the product on the current version.
